Build A Wrapping Chip Layout With The SwiftUI Layout Protocol

This article provides a detailed tutorial on creating a wrapping chip layout in SwiftUI using the Layout protocol, which is available from iOS 16 and macOS 13 onwards. It explains how to implement a custom layout that automatically flows tags, filters, or category pills onto the next line when they exceed the available width, avoiding fragile GeometryReader-based approaches. The guide includes complete code for a WrappingChipsLayout struct, covering the sizeThatFits and placeSubviews methods, row calculation logic, and integration with selectable filter chips. It also discusses availability checks for older OS versions and best practices for robust layout behavior.
