RBStack

RBStack is a straightforward library built using Swift's Result Builder, designed to create UIStackViews declaratively, much like VStack/HStack in SwiftUI.

This library is ideal for migrating existing UIKit code to improve readability and can potentially reduce UI code by 50%.

Requirements

• iOS 12.0+
• Swift 5.9+
• Xcode 15+

Features

• RBVStack and RBHStack to construct vertical and horizontal stack views. Kinds of child view expressions supported inside the builder closure including:
  • Optional
  • If-Else
  • For Loop
  • Array
  • Assignment statement
• RBSpacer and RBDivider to simplify layout management.

Swift Package Manager

You can add RBStack via Xcode or by editing Package.swift.
