Hi,

I'm developing an app using SwiftUI for both iOS and Mac OS and use onOpenURL to handle external links. However, this doesn't seem to work after switching to a single window app on Mac OS.

This code works:

WindowGroup {
    Text("Hi").onOpenURL { url in
        print("Open URL", url)
    }
}

But this doesn't:

Window("My App", id: "my_app") {
    Text("Hi").onOpenURL { url in
        print("Open URL", url)
    }
}

Anyone knows a workaround? Thanks!

Eventually solved it using a custom app delegate:

final class AppDelegate: NSObject, NSApplicationDelegate {
    var openUrlCallback: ((_ url: URL) -> Void)?

    func application(_ application: NSApplication, open urls: [URL]) {
        for url in urls {
            openUrlCallback?(url)
        }
    }
}

struct MyApp: App {
    @NSApplicationDelegateAdaptor(AppDelegate.self) var appDelegate

    var body: some Scene {
        Window("My App", id: "my_app") {
            Text("Hi").onAppear {
                appDelegate.openUrlCallback = { url in
                    print("Open URL", url)
                }
            }
        }
    }
}
