ArrangeUI is a supplemental UIKit package made up of views (HStackView, VStackView, PaddingView, SpacerView, etc) that employ a SwiftUI-like layout strategy.
This library makes it easy to build layouts that would otherwise be cumbersome to accomplish with resizing-masks, Auto Layout constraints, or raw frame-based layouts.
The layout strategy works as follows: a parent view proposes a size to its child view, typically its bounds, and the child responds with its ideal fitting size. The parent-view honors the child-view's reported size and positions it accordingly.
To accomplish this ArrangeUI views leverage the UIView's existing arrangement methods (intrinsicContentSize, sizeThatFits, and layoutSubviews) and tap into the UIKit view-tree render mechanism.
All ArrangeUI views are frame-based under-the-hood and fully compatible with all the aforementioned layout techniques used in UIKit.
This library is intended for UIKit developers that want to leverage SwiftUI layout strategies but aren't ready or interested in making a full transition to SwiftUI. Additionally, this library provides insight into how SwiftUI views and layouts may be implemented under-the-hood.
To install using Swift Package Manager, add this to the dependencies section in your Package.swift file:
.package(url: "https://github.com/danielinoa/ArrangeUI.git", .branch("main"))coming soon...
ArrangeUI, unlike SwiftUI, is exclusively concerned with views and layouts. It does not manage the lifecycle of your view objects and does not opine on how state should be propagated to said views.
Feel free to open an issue if you have questions about how to use ArrangeUI, discovered a bug, or want to improve the implementation or interface.
ArrangeUI is primarily the work of Daniel Inoa.
