Swiftui Uikit Interop

A practical reference for moving between SwiftUI and UIKit when you need camera controllers, document scanners, attributed text, or any of the hundred UIKit components still missing native SwiftUI equivalents. The guide walks through UIViewRepresentable and UIViewControllerRepresentable with clear lifecycle tables showing when makeUIView versus updateUIView fires, plus coordinator patterns for delegate callbacks. Targets iOS 26 with Swift 6.3 but notes backward compatibility to iOS 16. Most valuable for the state synchronization patterns and the common mistakes section, since getting binding updates to flow correctly across the framework boundary is where most interop bugs live. Good for incremental migrations or just wrapping that one UIKit view you can't replace yet.
