It looks like Apple has added some new API(s) to SFSpeechRecognition My app, which is currently listed on App Store does feature speech recognition. Yet, trying to use it under iOS 18.0 throws errors: -[SFSpeechRecognitionTask localSpeechRecognitionClient:speechRecordingDidFail:]_block_invoke Ignoring subsequent local speech recording error: Error Domain=kAFAssistantErrorDomain Code=1101 "(null)" What happens is that after several words are transcribed and displayed, the next sentence results in previous words disappearance. That's probably what that portion of the error text - "Ignoring subsequent local speech recording error: Error Domain=kAFAssistantErrorDomain Code=1101 "(null)" means. The problem occurs ONLY when the app is running under iOS 18.0 Even when it's compiled in Xcode 16.0 using iOS 17.5 everything works fine. Any suggestions?

Finally, there's a good news: in iOS 26 RC the problem - Speech Recognition in custom implementation - appears to be fixed! No more disappearing of the transcribed text after a pause. At least in my tests/trials of this functionality, it works as it did before upgrading to iOS 18. Thank you, Apple!

Also, I forgot to mention above. The bug resolution also had:

Recent Similar Reports:None

This despite the fact that my written description explicitly included this verbiage:

@righteoustales No reply for me either. Apparently, this bug has low priority. Nevertheless, it would be a matter of curtesy if not respect on the part of Apple toward developers (respect, by the way, they swear on all the time) to at least drop a line informing that the report(s) are on the backlog and will be looked at when the time permits.

I haven't gotten a reply on my report either. But I'm seeing the behavior on the developer 18.1 beta has reverted back to the pre 18.0 behavior.

I'm worried that solutions to this bug could give users an inconsistent experience if/when they update to 18.1

A slim hope. Somebody on the Internet has claimed that the bug is recognized by Apple internally. https://forums.getdrafts.com/t/ios-18-macos-15-beta-warning-for-dictation-users/15334

That's good to hear! I also encourage anyone else who comes here to take a look at my solution here https://forums.developer.apple.com/forums/thread/762952?answerId=804689022#804689022. Although the behavior isn't consistent (capitalizing new text), it at least stops the text from being wiped between pauses

Alas, my enthusiasm was a little bit premature. While my iPhone running iOS 26 proves that the problem has been fixed, somebody's iPad (though running at the moment iPadOS 18), despite getting the app being compiled and installed from Xcode 26, shows the bug being still there. How come that iOS 26 does have a fix, but iPadOS 26 does not (I checked on Simulater as well).
