Subspecs

All available features are avaiable in separated subspecs:

Core

Basic extenstion for basic swift types, like: CGRect, CGPoint, Sequence, UIColor etc. For example very usefull safe index access:

guard let model = models[safe: index] else { return }

Geometry

Some useful basic geometry concepts such as Ray, Line or Segment;

Vectors

Added SIMD vectors type conformance to some CoreGraphics and UI structs: CGPoint, CGRect, UIEdgeInsets, etc. Also Useful operators set for manipulating basic UIKit/CoreGraphics types as multi-dimensional vectors. For example CGRect and UIEdgeInsets both are 4d vectors. It lets client do the following:

let rect: CGRect
let insets: UIEdgeInsets
let rectWithInsets = rect + insets
let bounds = CGRect([0, 0, 640, 1136])
let size = CGSize([120, 60])
let origin = bounds.midpoint - (size * 0.5).pointValue
let frame = CGRect(origin: origin, size: size)

String

To calculate and cache String and NSAttributedString text size. Also, the ability to convert and cache HTML to NSAttributedString using NSAttributedString.DocumentType.html.

UI

Cool utils for UIView, such as

func addSubviews(_ subviews: [UIView])
func addSubviews(_ subviews: UIView...)

Custom views: GradientView, PathView

Accessor for setting shadow:

view.shadow = .init(color: shadowColor, blur: 10.0, opacity: 0.5, offset: .zero, path: nil)

Sketch/Zeplin shadow also:

view.shadow = .sketch(color: shadowColor, alpha: 0.5, bounds: shadowBounds, x: 0.0, y: 10.0, blur: 10.0, spread: 0.0)

UIExtension

Most useful is UIScalable protocol to let you work in the same proportions with the provided design. You need to setup smallets size from design as base value:

UI.setBaseWidths([.pad: 768, .phone: 375])

Then you can access adjusted value using .ui extension:

let width: CGFloat = 180.ui

Also, if you have separated modules or design, provided for you, have different screen sizes across the design. You can use Intent associated with your module:

UI.setBaseWidths([.pad: 768, .phone: 320], for: Module.intent)
// then you can access 
let width: CGFloat = 180.uiValue(for: Module.intent)

Boxed

Box container for mutability properties in immutable containers: N.B.! makes runtime increase retain count for Boxed object every time when struct with Boxed object passed via param into function

struct SomeData {
  let a = 1
  var b = 2.0
  let c = Boxed(false)
}

let immutable = SomeData()
immutable.a = 2 // is forbidden

var mutable = SomeData()
mutable.b = 2.0 // is valid for mutable instances

// is valid for both cases
immutable.c.value = false 
mutable.c.value = true

Associatable

Makes using ObjC runtime association easier:

private enum SomeClassYouWantToExtendViaObjcAssociationConst {

    static var propertyName = 0

}

extension SomeClassYouWantToExtendViaObjcAssociation {

    var readwriteValue: PropertyType? {
        get { return associated.value(for: &SomeClassYouWantToExtendViaObjcAssociationConst.propertyName) }
        set { associated.set(newValue, for: &SomeClassYouWantToExtendViaObjcAssociationConst.propertyName) }
    }

}

Flowable

Amazing and useful extensions for the creation and simultaneous object setup in-place. For example:

let label = UILabel {
  $0.text = "Text"
  $0.numberOfLines = 2
}

FormatterPool

Tools for creation and cache different types of formatters. For Dates, DateInterval, Length, PersonNameComponents etc.

  let date = Date()
  let locale = Locale.current
  let template = "EEEEEEE, d MMM"
  let dateFormat = DateFormatter.dateFormat(fromTemplate: template, options: 0, locale: locale) ?? template
  let dateString = DateFormatter.cached(format: dateFormat, locale: locale)
      .string(from: date)
