Platform

Using the UIKitChain framework, You can create a UIKit component in one line of code.

Installation

CocoaPods

CocoaPods is a dependency manager for Cocoa projects. You can install it with the following command:

$ gem install cocoapods

To integrate UIKitChain into your Xcode project using CocoaPods, specify it in your Podfile:

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '12.0'
use_frameworks!

target '<Your Target Name>' do
    pod 'UIKitChain', '~> 1.0.0'
end

Then, run the following command:

$ pod install

Swift Package Manager

Swift Package Manager is a tool for managing the distribution of Swift code. It’s integrated with the Swift build system to automate the process of downloading, compiling, and linking dependencies.

Xcode 11+ is required to build UIKitChain using Swift Package Manager.

dependencies: [
    .package(url: "https://github.com/MnkGitBox/UIKitChain.git", .upToNextMajor(from: "1.0.0"))
]

Manually

If you prefer not to use either of the aforementioned dependency managers, you can integrate UIKitChain into your project manually.

Usage

Call the .chain method right after initializing the UI element. Then you can configure the element using dot notation and finally call .component to get your complete view element.

  • Without UIKitChain

let circleView = UIView()
circleView.backgroundColor = .green
circleView.layer.cornerRadius = 50
circleView.layer.borderColor = UIColor.black.cgColor
circleView.layer.borderWidth = 1
circleView.clipsToBounds = true
circleView.translatesAutoresizingMaskIntoConstraints = false
  • With UIKitChain
let circleView = UIView().chain.bgColor(.green).cornerRadius(50).clipToBounds(true).border(.black).activeAutoConstrant(false).component

Add Missing Method or Variable

If there is any missing method or variable, You can add by extending the UIKitChain with the corresponding UIKit element.

extension UIKitChain where Component: UIView {
    @discardableResult
    func roundView() -> Self {
        component.layer.cornerRadius = component.bounds.height/2
        return self
    }
}
