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 yourPodfile:

source'https://github.com/CocoaPods/Specs.git'platform:ios,'12.0'use_frameworks!target'<Your Target Name>'dopod'SnapKit','~> 5.7.0'end

Then, run the following command:

$ pod install

Carthage is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks.

You can install Carthage withHomebrew using the following command:

$ brew update$ brew install carthage

To integrate SnapKit into your Xcode project using Carthage, specify it in yourCartfile:

github "SnapKit/SnapKit" ~> 5.0.0

Runcarthage update to build the framework and drag the builtSnapKit.framework into your Xcode project.

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 SnapKit using Swift Package Manager.

To integrate SnapKit into your Xcode project using Swift Package Manager, add it to the dependencies value of yourPackage.swift:

dependencies:[.package(url:"https://github.com/SnapKit/SnapKit.git",.upToNextMajor(from:"5.0.1"))]

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

import SnapKitclassMyViewController:UIViewController{    lazyvarbox=UIView()overridefunc viewDidLoad(){        super.viewDidLoad()self.view.addSubview(box)        box.backgroundColor=.green        box.snp.makeConstraints{(make)->Voidin           make.width.height.equalTo(50)           make.center.equalTo(self.view)}}}

You can try SnapKit in Playground.

Note:

To try SnapKit in playground, openSnapKit.xcworkspace and build SnapKit.framework for any simulator first.
