UILab

UILab is a simple group of extension framework designed to streamline and simplify the process of setting constraints in Swift-based UIKit projects for personal usage.

Installation

Integrate UILab into your project using your preferred dependency manager (Swift Package Manager, CocoaPods, or Manuel). Detailed installation instructions can be found in the further in the Readme.

Swift Package Manager

UILab is available through SPM. To Install it

• Go File -> Swift Packages -> Add Package Dependency
• Enter https://github.com/yasinkbas/UILab
• Click Add Package

Manual

You can also manually integrate UILab into your project by downloading it from here.

CocoaPods

UILab no longer supports Cocoapods, but you can still use the latest version 0.3.2 on Cocoapods. To install it, add the following line to your Podfile:

pod 'UILab'

Usage

Begin creating constraints using the concise and expressive syntax provided by UILab. Whether you're working with views, labels, buttons, or any other UI element, UILab aims to simplify the process.

Setting Constraints

You can use UILab as a matter of your taste. There are 3 ways to set constraints.

1. With Set Function

class ViewController: UIViewController {
  private lazy var containerView = UIView()

  override func viewDidLoad() {
    super.viewDidLoad()

    view.addSubview(containerView)
    containerView.set(.center(view), .width(100), .height(100))
  }
}

2. With Subscript

class ViewController: UIViewController {
  private lazy var containerView = UIView()

  override func viewDidLoad() {
    super.viewDidLoad()

    view.addSubview(containerView)
    var containerViewConstraints = containerView[.center(view), .width(100), .height(100)]
    containerViewConstraints.commit = true // activate
  }
}

Note: When using subscript style, you must set commit true to activate it.

3. With ResultBuilder

class ViewController: UIViewController {
  private lazy var containerView = UIView()

  override func viewDidLoad() {
    super.viewDidLoad()

    view.addSubview(containerView)
    containerView.set {
      ConstraintType.center(view, x: 9, y: 9)
      ConstraintType.width(100)
      ConstraintType.height(100)
    }
  }
}

Constraint Types

You can check all the available constraint types under ConstraintType here.

Getting Constraints

You can save for later your constraints before committing or retrieve them easily with get function.

Get constraints before committing

var contraintsYouWannaHold: Constraints?
func setup() {
 contraintsYouWannaHold = myView[.center(anotherView), .width(100), .height(100)]
 contraintsYouWannaHold?.commit = true // set true, when you want to activate it 
}

Getting active view constraint

let myViewHeightAnchor = myView.get(.height).first

Example

To help you grasp the simplicity and power of UILab, let's delve into a few practical examples showcasing how to set constraints for common UI scenarios in example project.

Note: To run the example project, clone the repo, and run pod install from the Example directory first.
