SOLVED: Launch app from website link

Forums > macOS

Good morning

Looking for a way to launch my psotal service barcode app from an URL and found this page:


But this describes an old method using AppDelegate....

Would this have to use now as well this snippet like for push notifications?

struct WedernochApp: App {
    @UIApplicationDelegateAdaptor(AppDelegate.self) var appDelegate
    var body: some Scene {
        WindowGroup {


Ah no...there is no AppDelegateAdaptor for macOS.....

Is there another method to add Apple Event receiver for URLScheme?


Ah no...there is no AppDelegateAdaptor for macOS.....

There is: NSApplicationDelegateAdaptor | Apple Developer Documentation


Right...forgot the good old NextStep workstation I had (o;

So this just works fine:

struct BarcoderApp: App {
    @NSApplicationDelegateAdaptor private var appDelegate: AppDelegate
    var body: some Scene {
        WindowGroup {

        Settings {

class AppDelegate: NSObject, NSApplicationDelegate {
    open func applicationWillFinishLaunching(_ notification: Notification) {
        print("Will Finish Launching")

And YESSS...Safari can launch now my Barcoder App ;-)

Now onto parsing URL parameters....


Hmm...looks good.....

klingler@Mac-mini-Arbeitszimmer ~ % /Applications/Barcoder.app/Contents/MacOS/Barcoder
Will Finish Launching
