Wrap UIKit views in SwiftUI by creating a UIViewRepresentable struct, implementing makeUIView and updateUIView methods, and managing UIKit delegate callbacks via a Coordinator to synchronize state across boundaries.

Embed SwiftUI inside UIKit screens by initializing a UIHostingController with your SwiftUI view, then adding it as a child view controller to coordinate data flow and state synchronization across the UIKit and SwiftUI boundaries.

Migrate UIKit apps to SwiftUI incrementally by wrapping individual UIKit surfaces like camera, maps, document pickers, and text editors with representable wrappers, ensuring safe and predictable interoperation during the transition.

Coordinator-based delegation assigns a Coordinator class to handle UIKit view delegate callbacks, intercepting events and synchronizing state updates across the UIKit and SwiftUI boundaries for predictable integration.

UIHostingController supports environment bridging by passing SwiftUI environment values to hosted views, ensuring consistent state and contextual data flow when embedding SwiftUI components inside UIKit view controllers.

UIViewRepresentable wrappers fail to update SwiftUI state when delegate callbacks are not routed through the Coordinator, breaking the state synchronization bridge between the UIKit view and the SwiftUI interface.
