Do you try to launch in simulator or on device ? First try on simulator. Then, in Xcode, select your app name at the top of the list in the left panel (the file browser panel). select TARGETS select Signing and Capabilities Do you notice any error indicated there ? What do you get here, precisely ? Why have you co.hashyap… and not com.hashyap… Also try to do an option-clean-build-Folder in Xcode (Product menu).

Do it here (and test with the print): func applicationWillTerminate(_ application: UIApplication) { // Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:. print("End") // Save here }

Thanks for feedback. So you were launching on device. Don't forget to close the thread.

Looks like you got the answer in SO. So, file a bug report.

The URL also points to some local location with sandbox in the name. You test on device, not simulator ? Could you show the url ?

Have you checked the images are available in target ? Could try to copy them to xcassets.

shows like the first picture with label and texts Do you mean launch screen ?

nor overload the optional == operator.  Yes, so it applies the == for instances (compares references). What I said is that even when you overload, that may still be the case. So I don't understand your last point.

I fear there is little to do… I've tried many combinations with no avail; always 950 results found: appgroup && catalyst appgroup AND catalyst appgroup .AND. catalyst appgroup | catalyst (in case pipes worked) appgroup, catalyst That was already the case in older forum: https://developer.apple.com/forums/thread/36927

while showing the notification in Spanish; the description shows in Spanish and the action buttons are in English and vice-versa Which buttons precisely ? What is the iPhone language setting ? I do not find where you tried to ;localise those buttons ; if so, they are displayed in the language of settings.

Good point. But look at this, where it explains how protocol are or are not overload. https://stackoverflow.com/questions/42283715/overload-for-custom-class-is-not-always-called So it seems, in your case, the == operator used is not the one you overloaded. Unless you also implement isEqual() … It is really a bit tricky.

Why not simply write @State private var name: String = "" @ObservedObject var use = Use(name: "") Have a look here for some details: https://developer.apple.com/forums/thread/128366

ASAP is not a word for this forum. No one is here to answer on notice🙂. Even if that were possible, you could not submit to appstore: Starting April 2021, all iOS and iPadOS apps submitted to the App Store must be built with Xcode 12 and the iOS 14 SDK.
