I've found multiple leaks in AVSpeechSynthesizer which are plaguing my users. My users are complaining of crashes due to this.
Ive created a feedback item (FB12212129) with a sample project attached which demonstrates one of the leaks. I'm hoping an engineer notices this. The only way ive hade my feedback noticed in the past is by both creating a feedback item AND posting on the forums. So here's my forum post. Help is much appreciated!
This seems to be fixed in the iOS 17 beta
I also see a lot of problems in TTS. Nothing is fixed, turn on Address Sanitizer in Xcode, it will crash immediately due to some memory issues (not on simulator). Please report on apple ´s feedbackassistent.
The memory leak that I was seeing seems to be fixed in iOS 17 but it still has performance issues. For example, it doesn't stop speaking immediately when you call stop(.immediate)
@And0Austria Yup just noticed the same thing...TTS will crash with the AddressSanitizer turned on iOS17. They are freeing a wild pointer according to the AddressSanitizer.
Looks like every app that uses AVSpeechSynthesizer has undefined behavior. I've been working on a feature for my app for a couple of months that uses this API and now after updating to iOS 17 it abruptly stops and random points in an utterance. Maybe it'll work. Maybe it won't.
I reported FB13188396 and made a thread about the issue here: https://developer.apple.com/forums/thread/737685
Kind of depressing that this was known two months ago and still made it into the iOS 17 release.
I have reported similar issues with TTS in iOS17 here https://feedbackassistant.apple.com/feedback/13251414 You can not access the report, but you can mention this report to Apple in your own reports.
Got Xcode 15.3 Beta with iOS 17.2 fixes the problem
