Ok, got it sussed. The code is simpler, and the delegate method now fires with each nav request, allowing me to define different behavior for internal vs. external links. Here's the working code: import SwiftUI import WebKit struct SwiftUIWebView: UIViewRepresentable { let url: URL func makeUIView(context: Context) -> WKWebView { print("makeUIView called...") let webView = WKWebView() webView.navigationDelegate = context.coordinator return webView } func updateUIView(_ webView: WKWebView, context: Context) { print("updateUIView called...") let request = URLRequest(url: url) webView.load(request) } func makeCoordinator() -> Coordinator { print("makeCoordinator called...") let coord = Coordinator() return coord } @MainActor class Coordinator: NSObject, WKNavigationDelegate { func webView(_ webView: WKWebView, decidePolicyFor navigationAction: WKNavigationAction) async -> WKNavigationActionPolicy { print("Delegate called...") if let frame = navigationAction.targetFrame, frame.isMainFrame { print("Target is main frame...") return .allow } else { print("Target is external...") return .cancel } } } } The webView.navigationDelegate = context.coordinator line was absolutely key, and the following article... www.hackingwithswift.com/books/ios-swiftui/using-coordinators-to-manage-swiftui-view-controllers ...was a big help in getting the proper incantation for setting the navigationDelegate. Thanks again, @BabyJ, for pointing me in the right direction!

Thanks @BabyJ, but unfortunately, that doesn't work b/c "self" in this context is a NSObject and can't be assigned to a property of type WKNavigationDelegate. I've refactored from a struct to a class, and the compiler's not complaining, but it's still not working. I feel I'm grasping at straws at this point. Any other insights would be appreciated. Here's what I've got now... final class SwiftUIWebView: NSObject, WKUIDelegate, UIViewRepresentable, WKNavigationDelegate { let url: URL override init() { self.url = URL(string: "https://mydomain.com/page")! } func makeUIView(context: Context) -> WKWebView { let webView = WKWebView() webView.navigationDelegate = self webView.uiDelegate = self return webView } func updateUIView(_ webView: WKWebView, context: Context) { let request = URLRequest(url: url) webView.load(request) } func makeCoordinator() -> Coordinator { print("Coordinator called") return Coordinator() } @MainActor class Coordinator: NSObject, WKNavigationDelegate, WKUIDelegate { func webView(_ webView: WKWebView, decidePolicyFor navigationAction: WKNavigationAction) async -> WKNavigationActionPolicy { print("Delegate called...") if let url = navigationAction.request.url, url.host != "mydomain.com", await UIApplication.shared.open(url) { return .cancel } else { return .allow } } } }

Am I correct that extension ItemWebView should be extension NewsItemWebView in the accepted reply?
