Sirius 3.0

You want to add pod 'Sirius', '~> 3.0' similar to the following to your Podfile:

target 'MyApp' do
  pod 'Sirius', '~> 3.0'
end

Then run a pod install inside your terminal, or from CocoaPods.app.

Alternatively to give it a test run, run the command:

pod try Sirius

At a Glance

Swift is still a brand new language, which, very often, does not relieve the developer from writing a lot of boilerplate code. The main goal of Sirius framework is to simplify work with fundamental things in modern programming: the objects. Framework includes set of extensions for Swift’s native types and protocols, which makes programming easier and allows to save many lines of code.

How To Get Started

Copy content of Sirius folder to your project.

Use Sirius cocoapod

Requirements

iOS 9.0 and later
Xcode 8 and later

Note: For Swift 2.x use Sirius v1.0. For Swift 3.0 use Sirius v3.0.

Usage

Manipulation with objects

let object = SomeClass()

object.use { (object) in
    // Do several operations with object...
}

object.useAs(NSString.self) { (object) in
    // Do something with object casted to NSString type...
}

Both methods use and useAs support chain calls, so it’s possible to write something like this:

object.use { (object) in
    // Do several operations with object...
}.useAs(NSString.self) { (object) in
    // Do something with object casted to NSString type...
}.useAs(NSNumber.self) { (object) in
    // Do something with object casted to NSNumber type...
}

Since two methods above return receiver’s instance, you can use them with initializer like this:

let view = UIView().use { (object) in
    object --> .blueColor()
    object.clipsToBounds = true
}

This approach makes code more demonstrative and clear.

Class name

let classNameIncludingNamespace = SomeClass.className(includeNamespace: true) // "com.domain.appName.SomeClass"
let classNameWithoutNamespace = SomeClass.className(includeNamespace: false) // "SomeClass"

Real-life examples

Usually, when you want to set up view’s layer, for example - make corners rounded, you write a code like this:

view.layer.backgroundColor = UIColor.whiteColor().CGColor
view.layer.borderColor = UIColor.blackColor().CGColor
view.layer.borderWidth = 1.0
view.layer.cornerRadius = view.bounds.size.width / 2.0
view.layer.masksToBounds = true

With Sirius you can forget about view. input on each line:

view.layer.use { (layer) in
    layer.backgroundColor = UIColor.whiteColor().CGColor
    layer.borderColor = UIColor.blackColor().CGColor
    layer.borderWidth = 1.0
    layer.cornerRadius = view.bounds.size.width / 2.0
    layer.masksToBounds = true
}

The same you can do on initialization of the view:

let view = UIView().use { (view) in
    view.frame = CGRect(x: 0.0, y: 0.0, width: 200.0, height: 200.0)

    view.layer.use({ (layer) in
        layer.backgroundColor = UIColor.whiteColor().CGColor
        layer.borderColor = UIColor.blackColor().CGColor
        layer.borderWidth = 1.0
        layer.cornerRadius = view.bounds.size.width / 2.0
        layer.masksToBounds = true
    })
}
