Requirements

  • iOS 9.0+
  • Xcode 9.0+
  • Swift 4.0+

Installation

CocoaPods

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

$ gem install cocoapods

CocoaPods 1.1+ is required to build Alamofire 4.0+.

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

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '9.0'
use_frameworks!

target '<Your Target Name>' do
    pod 'LayoutAnchor', '~> 4.0'
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 LayoutAnchor into your Xcode project using Carthage, specify it in your Cartfile:

github "yume190/LayoutAnchor" ~> 4.0

Run carthage update --platform ios to build the framework and drag the built LayoutAnchor.framework into your Xcode project.
