Yoga-SwiftUI

Yoga-SwiftUI is a powerful layout library for SwiftUI which brings Facebook’s Yoga flexbox implementation to SwiftUI. It offers a simple API to apply flexbox-based layout in your SwiftUI apps.

Features

Support for iOS (16+), macOS (13+), watchOS (9+) using SwiftUI custom layout.
A thin wrapper around Yoga, a cross-platform layout library from Facebook, bringing flexbox to SwiftUI
Nesting of Flex views within one another to build complex layouts
Full compatibility with Figma’s auto layout, empowering Figma plugin creators to generate flexbox code. It supports all properties including row gap and column gap in flexbox.
Supports a wide array of layout customization like justifyContent, alignItems, alignSelf, flexDirection, flexWrap, flexGrow, flexShrink and more

Usage

You can easily create a Flex container and add child views to it.

Flex(direction: .row, justifyContent: .center, alignItems: .center) {
    Text("Hello")
    Text("World")
}

In the above example, we create a Flex container with a row direction and center alignment for both axis. Inside it, we add two Text views.

Flex can be easily nested within one another to create complex layouts:

Flex {
    Flex(direction: .row) {
        Text("Row 1 Item 1")
        Text("Row 1 Item 2")
    }
    Flex(direction: .row) {
        Text("Row 2 Item 1")
        Text("Row 2 Item 2")
    }
}

In the above example, we have nested two Flex containers each with a row direction inside another Flex container.

The library also provides a set of modifiers to customize the layout of the SwiftUI views:

Text("Hello World")
    .flexGrow(1)
    .flexShrink(0)
    .justifyContent(.center)
    .alignItems(.flexStart)
    .alignSelf(.flexEnd)
    .flexDirection(.row)
    .flexWrap(.wrap)

In the above example, we use the modifiers provided by the library to customize the layout of a Text view.
