ComposeLayout

ComposeLayout is a DSL for Compositional Layout used in CollectionViews on iOS and MacOS. It is a part of ListKit that I previously developed and released. I have extracted the Compositional Layout configuration part from ListKit and re-released it as ComposeLayout.

Installation

ComposeLayout only support Swift Package Manager

dependencies: [
    .package(url: "https://github.com/skyfe79/ComposeLayout.git", from: "0.0.2"),
]

Examples

Using ComposeLayout makes writing complex Compositional Layouts intuitive and easy, allowing for straightforward composition of layouts. When developing iOS apps with UIKit's UICollectionView, ComposeLayout can greatly simplify the process of expressing and managing the layouts of CollectionViews. Below is an example code of Compositional Layout representing a 2-column grid.

ComposeLayout { index, environment in
    Section {
        HGroup(repeatItems: 2) {
            Item()
                .width(.fractionalWidth(1.0))
                .height(.fractionalHeight(1.0))
        }
        .interItemSpacing(.fixed(10))
        .width(.fractionalWidth(1.0))
        .height(.absolute(44))
    }
    .interGroupSpacing(10)
    .contentInsets(leading: 10, top: 0, trailing: 10, bottom: 0)
}
.build()

The Example folder in this repository contains sample codes that have been rewritten using ComposeLayout for both iOS and MacOS. These examples are based on the Modern Collection Views officially distributed by Apple.
