Cassowary

Version Carthage compatible swiftpm compatible Swift 4.0

Cassowary is a swift implement of constraint solving algorithm Cassowary which forms the core of the OS X and iOS Autolayout . This project is start from a direct port of rhea,but after that ,a lot of optimization has been added to make it performent better.

Requirements

  • iOS 8.0+
  • Swift 4.2
  • Xcode 10

Installation

CocoaPods

CocoaPods is a dependency manager for Cocoa projects. Install it with the following command:

$ gem install cocoapods

To integrate Cassowary into your Xcode project using CocoaPods, specify it to a target in your Podfile:

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '8.0'
use_frameworks!

target 'MyApp' do
  # your other pod
  # ...
  pod 'SwiftCassowary'
end

Then, run the following command:

$ pod install

open the {Project}.xcworkspace instead of the {Project}.xcodeproj after you installed anything from CocoaPods.

For more information about how to use CocoaPods, see this tutorial.

Carthage

Carthage is a decentralized dependency manager for Cocoa application. To install the carthage tool, you can use Homebrew.

$ brew update
$ brew install carthage

To integrate Panda into your Xcode project using Carthage, specify it in your Cartfile:

github "https://github.com/nangege/Cassowary" "master"

Then, run the following command to build the Panda framework:

$ carthage update

At last, you need to set up your Xcode project manually to add the Cassowary framework.

On your application targets’ “General” settings tab, in the “Linked Frameworks and Libraries” section, drag and drop each framework you want to use from the Carthage/Build folder on disk.

On your application targets’ “Build Phases” settings tab, click the “+” icon and choose “New Run Script Phase”. Create a Run Script with the following content:

/usr/local/bin/carthage copy-frameworks

and add the paths to the frameworks you want to use under “Input Files”:

$(SRCROOT)/Carthage/Build/iOS/Cassowary.framework

For more information about how to use Carthage, please see its project page.

Swift Package Manager

To install Cassowary for use in a Swift Package Manager-powered tool, script or server-side application, add Cassowary as a dependency to your Package.swift file. For more information, please see the Swift Package Manager documentation.

.package(url: "https://github.com/nangege/Cassowary", from: "0.2.0")

Usage

import Cassowary

let v1 = Variable(),v2 = Variable, v3 = Variable()
let solver = SimplexSolver()
try? solver.add(v1 + v2 == 10)
try? solver.add(v1 - v2 == 2)
solver.solve()
print(solver.valueFor(v1)).  // 6
print(solver.valueFor(v2)).  // 4
