UIKit-SwiftUI Bridging

Systematic guidance for bridging UIKit and SwiftUI. Most production iOS apps need both — this skill teaches the bridging patterns themselves, not the domain-specific views being bridged.

digraph bridge {
    start [label="What are you bridging?" shape=diamond];

    start -> "UIViewRepresentable" [label="UIView subclass → SwiftUI"];
    start -> "UIViewControllerRepresentable" [label="UIViewController → SwiftUI"];
    start -> "UIGestureRecognizerRepresentable" [label="UIGestureRecognizer → SwiftUI\n(iOS 18+)"];
    start -> "UIHostingController" [label="SwiftUI view → UIKit"];
    start -> "UIHostingConfiguration" [label="SwiftUI in UIKit cell\n(iOS 16+)"];
