Installation
CocoaPods
CocoaPods is a dependency manager for Cocoa projects. You can install it with the following command:
$ gem install cocoapods
CocoaPods 1.1.0+ is required to build SnapKit 4.0.0+.
To integrate SnapKit into your Xcode project using CocoaPods, specify it in your Podfile:
source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '10.0'
use_frameworks!
target '<Your Target Name>' do
pod 'SnapKit', '~> 5.0.0'
end
Then, run the following command:
$ pod install
Carthage
Carthage is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks.
You can install Carthage with Homebrew using the following command:
$ brew update
$ brew install carthage
To integrate SnapKit into your Xcode project using Carthage, specify it in your Cartfile:
github "SnapKit/SnapKit" ~> 5.0.0
Run carthage update to build the framework and drag the built SnapKit.framework into your Xcode project.
Manually
If you prefer not to use either of the aforementioned dependency managers, you can integrate SnapKit into your project manually.
Usage
Quick Start
import SnapKit
class MyViewController: UIViewController {
lazy var box = UIView()
override func viewDidLoad() {
super.viewDidLoad()
self.view.addSubview(box)
box.backgroundColor = .green
box.snp.makeConstraints { (make) -> Void in
make.width.height.equalTo(50)
make.center.equalTo(self.view)
}
}
}
Playground
You can try SnapKit in Playground.
