I found a workaround! Will publish an open source solution when I have time. Please, poke me if you need it.

I had an idea that me and OP have this issue because we use shared App Group container. So I tried this workaround: Copied all fonts from shared container to Documents. Then install them from Documents. It didn't work. I suspect that even if we include fonts to the Bundle, skip UIAppFonts, add them using CTFontManagerRegisterFontsForURL - they will not work. 😔

Hi there! Same problem on WidgetKit complications extension. On Watch Series 10 it doesn't works - complication become blank, on Simulator however it does.

@darkpaw, any luck with this issue?

Test Wow! Looks like I can't delete this post. To mods: could you please enable post editing? I need to delete the .watchface link from the question.

I also have SE2 and constantly get various errors while debugging watchOS apps with Xcode. Connection is very unstable.

Similar issue: // Sending 'center' risks causing data races let granted = try await center.requestAuthorization(options: options) Silenced by using @preconcurrency: @preconcurrency import UserNotifications

I was able to resolve the issue by switching to URL Schema. The tricky part here, is that the schema should contain at least some path components. First I tried schemes like this: myapp-halloween:// And got the error when tried to save the Custom Product Page: ⚠️Your changes could not be saved. Try again later Initially it was unclear at all what's wrong here. I thought that maybe URL Schemes are not acceptable at all, so that's why we tried deeplinks. And got the similar error as OP: on the first attempt deeplink isn't activated even on iOS 18.2.1. But experementally I found that if you add some path components, like: myapp://halloween Then everything works fine. CPP submitted without issues and the scheme opens the app and the URL gets received.

I had the same issue, @SpaceGrey. You solved it by using "All Sizes", I solved it by staying at "Single Size" but replacing JPG with PNG.

@iphonegamedeveloper, any success? I guess if scheme isn't https or http that we can assume it's custom in most cases.

We ended up switching to another backend provider 😢 But I hope one day we will return to CloudKit, as it maturates and gets better.

You have to use Logger for that. It will output the messages to Console.app, as well as to Xcode console. However, you have to specify them as public, otherwise the message text will be hidden. Like this: import os.log let logger = Logger(subsystem: "com.kelin.vladimir", category: "Debug") // Log level: notice. Explicitly specified `public`. logger.notice("\("TEST", privacy: .public)") In order to protect your private data in prod, consider using #if DEBUG macro.

Check that intentClassName corresponds to old Siri Intent auto-generated class name. Declare your AppIntent struct as public.

Try marking the entire MyIntent struct as public. This advice worked for me.

One of GPTs suggested me to make App Intent declaration public. This actually worked.
