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 '' 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.

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 SnapKit using Swift Package Manager.

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

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

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.

Note:

To try SnapKit in playground, open

SnapKit.xcworkspace
and build SnapKit.framework for any simulator first.
