Build Status Pod Version Swift 5.0

const is a (another) type-safe and expressive Swift DSL for Auto Layout

Example

let topView = UIView()
topView.backgroundColor = .red
baseView.addSubview(topView)

let bottomView = UIView()
bottomView.backgroundColor = .blue
baseView.addSubview(bottomView)

topView.constraints { make in
  make.top.equalTo(.superview).withInset(50)
  make.left.equalTo(.superview).withInset(50)
  make.right.equalTo(.superview).withInset(50)
  make.bottom.equalTo(.centerY, of: .superview).withInset(25)
}

bottomView.constraints { make in
  make.top.equalTo(.bottom, of: .view(topView)).withOffset(50)
  make.left.equalTo(.superview).withInset(50)
  make.right.equalTo(.superview).withInset(50)
  make.bottom.equalTo(.superview).withInset(50)
}

This code produces the following result:

Features

  • Lightweight — the current version of const consists of less than 500 lines of code. Although this project may become larger with time, it's very unlikely that it will exceed 1000 lines

  • Familiar and expressive — const API is heavily inspired by SnapKit, so if you have any experience with it, you shouln't have any problems getting familiar with this library

  • Pure Swift — that's it. No Objective-C code or using any of its runtime features like associated objects

Installation

You can install const using CocoaPods:

pod 'Const', '~> 0.1'

Or using Swift Package Manager:

.package(url: "https://github.com/acedened/const.git", from: "0.1.0")
