In 27.01 Enhanced and Premium voices work correctly - so the problem is gone

I have opened the bug report: FB24653879

Thanks for your reply. This app is targeted at the Mac App Store because I want users to be able to download it. I will try to post the bug report.

As for me the dowloaded voices do not work in mac os 26.6.1 too - I posted to forum https://developer.apple.com/forums/thread/844422

But you publish iPhone and iPad list that support iOS 26. To plan an App that will work with SpeechTranscriber we definitely must have some information about the hardware that supports it. For example if SpeechTranscriber does not work on any iPhone and iPad it is not any sense to make App for using this Api. Also this Api does not work in Simulator, so the developer must buy the device that support this Api.

By "valid indices" I mean the indices that correspond the indices of characters in the start and end of selectedRange

Seems to be resolved in the latest public beta

No

Thanks Eskimo - crash level calculate very simple - you have 1000 users that use the App today - 3 have crash - your crash level is 99.7

I have 99.7% Crash-free users users statistic in Crashlytics. All the crashes are in system code - not in the my code. There is no stack corruption error. I have not idea why these crashes occur. So, I simply ask if that crash level is high or it is normal for iOS Apps

The same issue
