A super fast and easy-to-use layout library for iOS. FrameLayoutKit supports complex layouts, including chaining and nesting layout with simple and intuitive operand syntax.

It simplifies the UI creation process, resulting in cleaner and more maintainable code.

Why?

Say NO to autolayout constraint nightmare:

Autolayout
No Yes!!!

Installation

FrameLayoutKit is available through Swift Package Manager (Recommended) and CocoaPods:

Regardless, make sure to import the project wherever you may use it:

import FrameLayoutKit

Cocoapods:

FrameLayoutKit can be installed as a CocoaPod. To install, include this in your Podfile.

pod "FrameLayoutKit"

Example

Some examples of how FrameLayoutKit works:

Source Result 
let frameLayout = HStackLayout()
frameLayout + VStackLayout {
   ($0 + earthImageView).alignment = (.top, .center)
   ($0 + 0).flexible() // add a flexible space
   ($0 + rocketImageView).alignment = (.center, .center)
}
frameLayout + VStackLayout {
   $0 + [nameLabel, dateLabel] // add an array of views
   $0 + 10 // add a space with a minimum of 10 pixels
   $0 + messageLabel // add a single view
}.spacing(5.0)

frameLayout
   .spacing(15)
   .padding(top: 15, left: 15, bottom: 15, right: 15)
   .debug(true) // show dashed lines to visusrc="https://raw.github.com/kennic/FrameLayoutKit/master/ the layout
result 1
Source Result 
let frameLayout = VStackLayout {
  ($0 + imageView).flexible()
  $0 + VStackLayout {
     $0 + titleLabel
     $0 + ratingLabel
  }
}.padding(top: 12, left: 12, bottom: 12, right: 12)
 .distribution(.bottsrc="https://raw.github.com/kennic/FrameLayoutKit/master/.spacing(5)
result 1
Source Result 
let posterSize = CGSize(width: 100, height: 150)
let frameLayout = ZStackLayout()
frameLayout + backdropImageView
frameLayout + VStackLayout {
 $0 + HStackLayout {
  ($0 + posterImageView).fixedSize(posterSize)
    $0 + VStackLayout {
      $0 + titleLabel
      $0 + subtitleLabel
    }.padding(bottom: 5).flexible().distribution(.bottom)
  }.spacing(12).padding(top: 0, left: 12, bottom: 12, right: 12)
}.distrsrc="https://raw.github.com/kennic/FrameLayoutKit/master/on(.bottom)
result 2
Source Result 
let buttonSize = CGSize(width: 45, height: 45)
let cardView = VStackLayout()
  .spacing(10)
  .padding(top: 24, left: 24, bottom: 24, right: 24)

cardView + titleLabel
(cardView + emailField).minHeight = 50
(cardView + passwordField).minHeight = 50
(cardView + nextButton).fixedHeight = 45
(cardView + separateLine)
  .fixedContentHeight(1)
  .padding(top: 4, left: 0, bottom: 4, right: 40)
cardView + HStackLayout {
 ($0 + [facebookButton, googleButton, appleButton])
  .forEach { $0.fixedContentSize(buttonSize) }
}.distribution(.censrc="https://raw.github.com/kennic/FrameLayoutKit/master/spacing(10)
result 2

Two types of code syntax:

Regular syntax Chained syntax
frameLayout.distribution = .center
frameLayout.spacing = 16
frameLayout.isFlexible = true

frameLayout
  .distribution(.center)
  .spacing(16)
  .flexible()

DSL Syntax

In FrameLayoutKit, DSL (Domain Specific Language) syntax provides a more declarative and readable way to define layouts, much like SwiftUI. This syntax is particularly used in VStackView, HStackView, and ZStackView. These views support DSL, allowing you to add standard UIKit views directly or customize them with Item(view) for more control over size and position. It simplifies the process of creating and managing layouts by offering a SwiftUI-like declarative approach, making your code more readable and easier to maintain.

let titleLabel = UILabel()
let descriptionLabel = UILabel()
let actionButton = UIButton()

let vStackLayout = VStackView {
    titleLabel
    descriptionLabel
    SpaceItem(20) // Adds a space of 20 points
    Item(actionButton).minWidth(120) // Customizes the button's minimum width
}
