Simplifying Backwards Compatibility in Swift

Read Original

This article addresses the challenge of supporting new Swift/iOS features while maintaining backwards compatibility. It introduces a 'Backport' struct as a namespace to encapsulate availability checks, providing a cleaner API than inline conditional logic. The post includes a practical example for backporting the SwiftUI .badge() modifier to work on iOS versions prior to 15.
