Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

Past Releases

2.0.0 - 2023-05-02

Fixed

ConstrainedAspectRatio measures correctly in fitParent and fillParent modes when the proposed constraint has the same aspect ratio as the element's constraint.
ConstrainedAspectRatio adheres to the Caffeinated Layout contract when unconstrained in fitParent or fillParent, by reporting infinity instead of falling back to the constrained element's size.

Changed

Caffeinated Layout is enabled by default. You can disable it on a BlueprintView with the layoutMode property, or disable it globally by setting LayoutMode.default.

Deprecated

ConstrainedAspectRatio content mode fillParent is deprecated, due to having limited utility in Caffeinated Layout.

1.0.0 - 2023-04-18

Fixed

Restored documentation generation by executing the generate_docs.sh script with bundle exec to ensure gems are referenced properly.

Added

Introduced a new layout engine, Caffeinated Layout. Caffeinated Layout features a new API for custom layouts that is modeled after SwiftUI, and greatly improves performance.

To enable Caffeinated Layout globally, set LayoutMode.default to .caffeinated. To enable it for a single view, set the layoutMode property of a BlueprintView.

Caffeinated Layout is not enabled by default yet, but will be in a future release.
Added layoutMode to BlueprintViewRenderMetrics to expose which layout mode was used to render a Blueprint view.

Changed

The Layout and SingleChildLayout protocols have new methods to support Caffeinated Layout.

To improve performance, Caffeinated Layout requires elements to adhere to a new contract for sizing behavior. Many elements can be easily adapted to the new API, but certain behaviors are no longer possible, particularly with regard to behavior when the size constraint is unconstrained.

For more information about implementing these protocols and the sizing contract, see the Layout documentation.

Internal

Updated jazzy gem (0.14.3).
Updated cocoapods (1.12.0).
Updated Ruby version (2.7).

0.50.0 - 2023-03-07

Fixed

The Environment will now automatically inherit for BlueprintView instances nested inside UIViewElement during measurement.

Added

Introduced ElementContent.init(byMeasuring:), for use when your Element contains a nested BlueprintView, commonly used to implement stateful elements. This avoids detached measurements and improves performance.

Changed

Renamed BlueprintViewUpdateMetrics to BlueprintViewRenderMetrics.
Renamed BlueprintViewRenderMetrics.measureDuration to layoutDuration.
Renamed BlueprintViewMetricsDelegate.blueprintView(_:completedUpdateWith:) to blueprintView(_:completedRenderWith:).
BlueprintViewRenderMetrics values are now calculated using CACurrentMediaTime instead of Date.

Internal

Added an Internal section to the changelog. This section is intended to capture any notable non-public changes to the project.
ElementContent.init(child:) now utilizes a unique ContentStorage type, which improves layout performance.

0.49.1

Fixed

Image's aspectFill contentMode now measures the same as aspectFit to avoid aggressively taking up space when not necessary.

0.49.0

Fixed

Fixed unexpected measurement results that could occur from Images using the aspectFit contentMode.

0.48.1

Fixed

Fix Catalyst version specifier in SPM package.

0.48.0

Added

Added AccessibilityElement.CustomAction to allow custom actions for use by assistive technologies.
Added accessibilityCustomActions property to Label and AttributedLabel.
UIViewElementContext now passes through an environment property, enabling environment-dependent measurements and layouts.

Changed

Updated minimum deployment target from iOS 12 to iOS 14.
URLHandlerEnvironmentKey.defaultValue should now be a no-op in extensions.
Marks pod as APPLICATION_EXTENSION_API_ONLY

0.47.0

Added

accessibilityHint property for Label and AttributedLabel.

0.46.0

Fixed

When stacks lay out with more fixed magnitude than is available for layout, flexible items will no longer receive a negative width.

Changed

StackElement layouts have been optimized for the case of one fixed and one flexible element to improve performance. This also fixes issues as described in #265 in many cases.

0.45.1

Fixed

Improve AttributedLabel rendering performance.

0.45.0

Fixed

Fixed an issue where rounding was handled incorrectly for nested BlueprintViews.

Added

Added new logging option to expose aggregate measurements.

0.44.1

Fixed

AccessibilityContainer now omits accessibility elements where .accessibilityElementsHidden is true.

0.44.0

Added

Image now provides an override to prevent VoiceOver from generating accessibility descriptions.

0.43.0

Added

Introduced an Element.modify { ... } conditional, to allow changing properties on an element.

Changed

Aligned will now constrain its content to the provided layout frame. If you need content to exceed the layout frame, please use Decoration.
AccessibilityElement will now only return accessibilityPath for elements with a non-square corner style. This avoids needlessly changing AccessibilitySnapshot (https://github.com/cashapp/AccessibilitySnapshot) reference images.

0.42.0

Added

Introduced accessibilityFrameCornerStyle to AccessibilityElement.

0.41.0

Added

Added .grows and .shrinks to StackLayout.Child.Priority, to allow for extra control over how flexible elements grow and shrink.
AccessibilityBlocker now takes in a Bool to control blocking, to avoid changing the element hierarchy to toggle if blocking is occurring.

0.40.0

Added

Added support for optionals in builders without unwrapping via if let.
Static constants on Alignment are now public (such as Alignment.topTrailing).

Changed

AnimationAttributes has gained a .default option.
LayoutTransition has default values for its AnimationAttributes parameters.

0.39.0

Added

Added support for adjusting text spacing and sizing on AttributedLabel and Label when text does not fit within the provided layout rect.

Removed

MeasurementCachingKey has been removed – Blueprint has cached measurements per render pass for many releases, so this actually slowed down layouts due to additional allocations and cache checking. This is about a 5-10% performance improvement depending on the layout.

Changed

Accessibility increment, decrement actions have been moved to associated values on the AccessibilityElement.Trait enum.

0.38.0

Added

Shadows on Label and AttributedLabel
Accessibility increment, decrement and activate actions now available on AccessibilityElement
Decorate has a new aligned positioning, that uses stack-style Alignment values and alignment guides.
The context vended to custom Decorate positions includes the decorated content size.

Changed

The context vended to custom Decorate positions was renamed to PositionContext, and the contentFrame property was replaced with a contentSize.

0.37.0

Fixed

Decorate will now properly scale its base content to the full size of the rendered element, if the measured and laid out sizes differ.
Fixed an issue where AttributedLabel could cause a crash when voice over was enabled.

Added

LayoutWriter.Context now exposes the layout phase, to differ any calculations between measurement and layout.

0.36.1

Fixed

Fixed an issue where AttributedLabel and Label would not pass touches to super views when expected.

0.36.0

Fixed

Fixed an issue where AttributedLabel might not detect link taps in multi-line labels.
.aligned(vertically:horizontally:) now has the correct default values to match the Aligned initializer.

Changed

The default line break mode for Label is now byTruncatingTail, matching the default for UILabel. (It was previously byWordWrapping, which does not indicate that truncation occured.)
AttributedLabel will normalize certain line break modes based on the number of lines.

0.35.1 - 2022-01-13

Fixed

Label and AttributedLabel now correctly report their UIAccessibilityTraits.

0.35.0 - 2022-01-11

Added

Added the EditingMenu element, which allows showing a UIMenuController (aka the system editing menu) on tap, long press, or based on a trigger.

Changed

Label.font now defaults to using a font of size UIFont.labelFontSize (17) instead of UIFont.systemFontSize.

0.34.0 - 2021-12-16

Added

Support CALayerCornerCurve for Box corner styles.
Added AttributedText, which supports applying strongly-typed attributes to strings (much like the AttributedString type introduced in iOS 15).
Added support for links to AttributedLabel:
- Links can be added using the link attribute of the attributed string. This attribute supports URLs or Strings.
- The label also supports detecting certain types of data and links, much like UITextView. Use the linkDetectionTypes property to specify which types of data to detect.
- Links are opened using the LinkHandler in the environment, which by default uses UIApplication.shared.open(_:options:completionHandler:). Customize link handling by providing a URLHandler to the environment at the appropriate scope. AttributedLabel also has a function for easily handling links with a closure using the onLinkTapped method.

0.33.3 - 2021-12-8

Fixed

Fixed an issue where Box did not implicitly animate its shadow.

Changed

Reverted scroll view keyboard inset behavior to the behavior in 0.30.0, since the recent changes were causing unexpected issues.

0.33.2 - 2021-11-30

Fixed

Fixed an issue where ScrollView did not adjust its content inset correctly when the keyboard height or content insets changed.

0.33.1 - 2021-11-22

Fixed

Fixed an issue where BlueprintView would not size correctly when used with Auto Layout.

Added

Added an ElementContent variant whose measureFunction takes in both a SizeConstraint and an Environment.

0.33.0 - 2021-11-18

Added

Allow measuring within an explicit SizeConstraint in GeometryProxy.
Add an additional stackLayoutChild(priority:) method overload, for easier autocomplete when only customizing the layout priority.

Changed

Values returned from sizeThatFits and systemLayoutSizeFitting are now cached.

0.32.0 - 2021-11-16

Fixed

Fixed an issue where the keyboard inset adjustment was incorrect in some cases.
Fixed a retain cycle in @FocusState. (#285)

Added

Add support for for...in loops and available checks to result builder APIs.

0.31.0 - 2021-11-09

Fixed

intrinsicContentSize is now cached.

Added

Improved error messages when using result builders with optional values.

0.30.0 - 2021-10-15

Added

Added a Hidden element and .hidden() modifier for hiding elements.
Overlay now supports result builders.
SegmentedControl now supports result builders.

Removed

Removed deprecated initializer from AccessibilityElement which was causing ambiguous initializer errors.

Changed

UserInteractionEnabled has been moved from BlueprintUICommonControls into BlueprintUI. It no longer has a backing view, and instead uses layout attributes to apply itself to elements. This change shouldn't affect consumers.

0.29.0 - 2021-09-21

Added

The @FocusState property wrapper can be used to manage focus of text fields. (#259)

After binding a text field to a state, you can programmatically focus the field by setting the state value.

struct LoginForm: ProxyElement {
    enum Field: Hashable {
        case username, password
    }

    @FocusState private var focusedField: Field?

    var elementRepresentation: Element {
        // This text field will be focused when `self.focusedField = .username`
        TextField(text: "")
            .focused(when: $focusedField, equals: .username)
    }
}

Row, Column, EqualStack, and GridRow can now be initialized declaratively using result builders. ([#220])
- To declare one of these containers, simply include the elements inside the ElementBuilder trailing closure.
- To customize the container, pass values through the containers init or leave out to use the provided defaults parameters.
- To customize one of the child element's container specific properties (key, priority, etc), tack on a corresponding modifier such as stackLayoutChild() and gridRowChild().
```
let row = Row(alignment: .fill) {
  TestElement()
  TestElement2()
    .stackLayoutChild(priority: .fixed, alignmentGuide: { _ in 0 }, key: "two")
}
```
The accessibilityElement(...) modifier has been added for wrapping an Element in an AccessibilityElement. Note that this will override all accessibility parameters of the Element being wrapped, even if values are left unspecified or set to nil.
An initializer on AccessibilityElement that requires a label, value, and traits.
Overlay supports keys for disambiguation between view updates. (#264)

Changed

BlueprintView's intrinsicContentSize will now return UIView.noIntrinsicMetric if there is no element associated with it.
TextField's becomeActiveTrigger and resignActiveTrigger properties have been replaced with a focusBinding for use with the new @FocusState property wrapper.

Deprecated

The accessibility(...) modifier has been deprecated. Use accessibilityElement(...) instead.
An initializer on AccessibilityElement that allowed all parameters to be unspecified. Use the initializer with required parameters instead.
Overlay.add(_:) deprecated in favor of Overlay.add(key:child:).

0.28.1 - 2021-09-10

Added

View-backed elements may opt-in to a frame rounding behavior that prioritizes preserving the frame size rather than the frame edges. This is primarily meant for text labels, to fix an issue where labels gain or lose a pixel in rounding and become wrapped or truncated incorrectly. (#257)

Changed

Lifecycle hooks are guaranteed to run after all views are updated. (#260)

0.28.0 - 2021-09-01

Fixed

Fixed an issue where Label and AttributedLabel were not accessibility elements.

Added

Label AttributedLabel and TextField elements now support configuration of accessibility traits.
The Environment is now automatically propagated through to nested BlueprintViews within a displayed Element hierarchy. This means that if your view-backed Elements themselves contain a BlueprintView (eg to manage their own state), that nested view will now automatically receive the correct Environment across BlueprintView boundaries. If you were previously manually propagating Environment values you may remove this code. If you would like to opt-out of this behavior; you can set view.automaticallyInheritsEnvironmentFromContainingBlueprintViews = false on your BlueprintView.

Lifecycle hooks. You can hook into lifecycle events when an element's visibility changes.

element
  .onAppear {
    // runs when `element` appears
  }
  .onDisappear {
    // runs when `element` disappears
  }

Removed

Removed support for / deprecated iOS 11.

Changed

makeUIView() on UIViewElement is no longer a static function, to allow access to properties during view creation.

0.27.0 - 2021-06-22

Changed

The signature of Element.backingViewDescription(bounds: CGRect, subtreeExtent: CGRect?) -> ViewDescription? has changed to backingViewDescription(with context: ViewDescriptionContext) -> ViewDescription? (#231). This is a large breaking change, but is worth it as it allows us to pass additional context to backingViewDescription in the future in a non-breaking way. The ViewDescriptionContext contains the bounds and subtreeExtent, as well as the Environment the element is rendered in.

0.26.0 - 2021-06-02

Added

Add ScrollTrigger, which adds the ability set the content offset of a ScrollView
Add UIViewElementContext to UIViewElement.updateUIView. The context currently has one property, isMeasuring, which tells you if the view being updated is the static measuring instance.

0.25.0 - 2021-05-5

Changed

Expose contentInsetAdjustmentBehavior on ScrollView.

0.24.0 - 2021-04-16

Added

Add Keyed element, which can be used to help differentiate elements during the diff and update process, eg to assist with proper animation transitions.
Introduce GridRow, a Row alternative suited for columnar layout. GridRow supports the following:
- spacing
- vertical alignment
- children with absolutely-sized widths
- children with proportionally-sized widths¹
¹Proportional width in this case always means "a proportion of available layout space after spacing and absolutely-sized children are laid out."

Example:
```
GridRow { row in
  row.spacing = 8
  row.verticalAlignment = .center
  row.add(width: .absolute(50), child: authorLabel)
  row.add(width: .proportional(0.75), child: bodyLabel)
  row.add(width: .proportional(0.25), child: dateLabel)
}
```
Added support to LayoutWriter to allow specifying keys for child Elements.
Blueprint can now emit signpost logs during its render pass, which you can use for performance tuning. (#209)

Signpost logs are disabled by default. To enable them, set BlueprintLogging.enabled = true.

Changed

The layout system now uses a caching system to improve performance by eliminating redundant measurements. (#209)

0.23.0 - 2021-03-26

Added

Introduce UserInteractionEnabled, an element which conditionally enables user interaction of wrapped elements.

searchField
    .userInteractionEnabled(canBeginSearch)

Changed

Change ProxyElement to directly return the content of a child. This significantly speeds up deeper element hierarchies that are made up of proxy elements, by reducing the duplicate calculation work that needs to be done to layout an element tree.
Change backing view of TransitionContainer to not directly receive touches while still allowing subviews to do so.

0.22.0 - 2021-03-15

Added

Introduce Decorate to allow placing a decoration element in front or behind of an Element, without affecting its layout. This is useful for rendering tap or selection states which should overflow the natural bounds of the Element, similar to a shadow, or useful for adding a badge to an Element.

0.21.0 - 2021-02-17

Added

Introduce conditionals on Element to allow you to perform inline checks like if, if let, and map when building Element trees.

Changed

Introduce additional APIs on Overlay to ease conditional construction the Overlay elements.

0.20.0 - 2021-01-12

Added

Add Transformed element to apply a CATransform3D to a wrapped element.

0.19.1 - 2021-01-06

Removed

Remove compile time validation from Elements, since it caused compile-time errors in certain cases when extensions and where clauses were used.

0.19.0 - 2021-01-05

Fixed

~~Ensure that Elements are a value type. This is generally assumed by Blueprint, but was previously not validated. This is only validated in DEBUG builds, to avoid otherwise affecting performance.~~

Added

Add LayoutWriter, which makes creating custom / arbitrary layouts much simpler. You no longer need to define a custom Layout type; instead, you can just utilize LayoutWriter and configure and place your children within its builder initializer.

0.18.0 - 2020-12-08

Added

Add AccessibilityContainer.identifier ([#180])

0.17.1 - 2020-10-30

Fixed

Fixed an issue where view descriptions were applied with unintentional animations while creating backing views. This could happen if an element was added during a transition. (#175)
Fixed pull-to-refresh inset for iOS 13+. (#176)

0.17.0 - 2020-10-21

Added

Add alignment guides to stacks. (#153)

Alignment guides let you fine-tune the cross axis alignment. You can specifying a guide value for any child in that element's coordinate space. Children are aligned relatively to each other so that the guide values line up, and then the content as a whole is aligned to the stack's bounds.

In this example, the center of one element is aligned 10 points from the bottom of another element, and the contents are collectively aligned to the bottom of the row:
```
Row { row in
    row.verticalAlignment = .bottom

    row.add(
        alignmentGuide: { d in d[VerticalAlignment.center] },
        child: element1
    )

    row.add(
        alignmentGuide: { d in d.height - 10 },
        child: element2
    )
}
```

Removed

Removed support for iOS 10. Future releases will only support iOS 11 and later.

Deprecated

Row alignments leading and trailing are deprecated. Use top and bottom instead. (#153)

0.16.0 - 2020-09-22

Fixed

Fixed EqualStack to properly constrain children when measuring. (#157)

Added

Add a new TransitionContainer.init that supports further customization during initialization and has the same defaults as ViewDescription. (#155, #158)
Add transition(onAppear:onDisappear:onLayout) and transition(_:) methods to Element to describe transition animations. (#155, #158)

Removed

Remove GridLayout; it's incomplete and was never really intended to be consumed widely. The intended replacement is putting EqualStacks inside of a Column, or Rows inside a Column.

Deprecated

TransitionContainer(wrapping:) is deprecated. Use the new TransitionContainer(transitioning:) instead. (#158)

Misc

Removed some redundant work being done during rendering. (#154)

0.15.1 - 2020-09-16

Fixed

Fixes a crash that can occur in Box when specifying a corner radius and shadow. (#149)

0.15.0 - 2020-09-14

Added

Add addFixed(child:) and addFlexible(child:) methods to StackElement for adding children with a grow & shrink priority of 0.0 and 1.0 respectively. (#143)

Add capsule case to Box.CornerStyle (#145). This addition sugars the following pattern:

GeometryReader { geometry in
  Box(cornerStyle: .rounded(geometry.constraint.height.maximum / 2.0))
}

into

Box(cornerStyle: .capsule)

Add accessibilityFrameSize to AccessibilityElement for manually specifying a size for the frame rendered by Voice Over. (#144)
Add Opacity element for modifying the opacity of a wrapped element. (#147)

Changed

BlueprintView will call layoutIfNeeded on backing views during its layout pass. This allows backing views' subviews that are laid out during layoutSubviews to participate in animations. (#139)

0.14.0 - 2020-08-12

Added

Add textColor property on TextField (#133).
Add the windowSize environment key. (#134)

Add GeometryReader. (#135)

This element allow you to compose elements whose contents depend on the amount of space available.

Here is an example that dynamically chooses an image based on the width available:

GeometryReader { (geometry) -> Element in
    let image: UIImage
    switch geometry.constraint.width.maximum {
    case ..<100:
        image = UIImage(named: "small")!
    case 100..<500:
        image = UIImage(named: "medium")!
    default:
        image = UIImage(named: "large")!
    }
    return Image(image: image)
}

Changed

Default ScrollView.delaysContentTouches to true (#132)

Misc

Set an explicit shadow path on Box (#137)

0.13.1 - 2020-07-30

Added

Introduce AccessibilityContainer element for wrapping an element with multiple sub-elements that should be in a voice over container.
Add font property on TextField (#127).

0.13.0 - 2020-07-20

Fixed

Update the scroll indicator inset when adjusting the content inset.
Label & AttributedLabel use an internal UILabel for measurement. This fixes measurement when there is a line limit set. However, it also means that the screen scale cannot be specified and is always assumed to be UIScreen.main.scale. These elements may not be measured correctly if they are placed on a screen other than UIScreen.main. (#120)

Added

Introduce MeasurementCachingKey, to allow for elements to provide a way to cache their measurement during layout passes. This provides performance optimizations for elements whose layout and measurement is expensive to calculate.

Introduce UIViewElement to make wrapping self-sizing UIViews easier.

You can now write a UIViewElement like this:

struct Switch : UIViewElement
{
  var isOn : Bool

  typealias UIViewType = UISwitch

  static func makeUIView() -> UISwitch {
      UISwitch()
  }

  func updateUIView(_ view: UISwitch) {
      view.isOn = self.isOn
  }
}

And the elements will be sized and presented correctly based on the view's sizeThatFits.

Add isAccessibilityElement to Label and AttributedLabel. (#120)
Add lineHeight to Label for specifying custom line heights. AttributedLabel has a textRectOffset property to support this. (#120)

Changed

Update Demo app to support more demo screen types.

0.12.2 - 2020-06-08

Fixed

Fix erroneous use of frame instead of bounds when laying out BlueprintView.

Added

Add delaysContentTouches to the ScrollView element.

0.12.1 - 2020-06-05

Fixed

Use default environment when measuring BlueprintView.

0.12.0 - 2020-06-04

Fixed

Removed layout rounding no longer needed since #64 (#95).

Added

Add support for the iPhone SE 2 in ElementPreview.
Added tintColor and contentMode into the initializer for Image. (#100)
Added an Empty element, to mirror EmptyView in SwiftUI. It is an element with no size and draws no content.

Environment (#101).

You can now read and write values from an Environment that is automatically propagated down the element tree. You can use these values to dynamically build the contents of an element, without having to explicitly pass every value through the tree yourself.

You can read these values with EnvironmentReader:

struct Foo: ProxyElement {
    var elementRepresentation: Element {
        EnvironmentReader { environment -> Element in
            Label(text: "value from environment: \(environment.foo)")
        }
    }
}

And set them with AdaptedEnvironment:

struct Bar: ProxyElement {
    var elementRepresentation: Element {
        ComplicatedElement()
            .adaptedEnvironment { environment in
                environment.foo = "bar"
            }
    }
}

Several enviroment keys are available by default (#102):

calendar
display scale
layout direction
locale
safe area insets
time zone

You can create your own by making a type that conforms to EnvironmentKey, and extending Environment with a new property:

extension Environment {
    private enum FooKey: EnvironmentKey {
        static let defaultValue: String = "default value"
    }

    /// The current Foo that elements should use.
    public var foo: String {
        get { self[FooKey.self] }
        set { self[FooKey.self] = newValue }
    }
}

0.11.0 - 2020-05-10

Fixed

Fixed ConstrainedSize to ensure that the measurement of its inner element respects the ConstrainedSize's maximum size, which matters for measuring elements which re-flow based on width, such as elements containing text.
Changed BlueprintView.sizeThatFits(:) to treat width and height separately when determining if measurement should be unconstrained in a given axis.

Added

Added support for SwiftUI-style element building within BlueprintUI and BlueprintUICommonControls.

This allows you to replace this code:

ScrollView(.fittingHeight) (
  wrapping: Box(
    backgroundColor .lightGrey,
    wrapping: Inset(
      uniformInset: 10.0,
      wrapping: ConstrainedSize(
        height: .atLeast(20.0),
        wrapping: Label(
          text: "Hello, world!"
        )
      )
    )
  )
)

With this code:

Label(text: "Hello, World!")
  .constrainedTo(height: .atLeast(20.0))
  .inset(by: 20.0)
  .box(background: .lightGrey)
  .scrollable(.fittingHeight)

Improving readability and conciseness of your elements.
