I have received the same error code 401 and it turned out that you need to wait up to 12-24 hours (in my case it was approximately 7 hours) after the creation of the private key until the verification succeeded with 200. Beyond this, you need to create a key for DeviceCheck and not for APN as stated by some examples. APN keys didn't work for me!

You could use caching player item and combine it with a cache.

Here is a workaround to resolve Key path value type 'WritableKeyPath<EnvironmentValues, WidgetFamily>' cannot be converted to contextual type 'KeyPath<EnvironmentValues, WidgetFamily>'. Source: https://stackoverflow.com/a/68489369 extension WidgetFamily: EnvironmentKey {     public static var defaultValue: WidgetFamily = .systemMedium } extension EnvironmentValues {   var widgetFamily: WidgetFamily {     get { self[WidgetFamily.self] }     set { self[WidgetFamily.self] = newValue }   } }

@edford, I can confirm seeing crash reports with 0x0 exception codes on iOS 15. My guess it is the watchdog killing the app, but I'm not sure. Please see FB9791707.
