Same issue here, for my case though, I used self.navigationItem.setValue(true, forKey: "__largeTitleTwoLineMode") and this enables the large title to be displayed without truncation but incurs the same issue as yours. For mine however, untruncated titles work fine. I am also very confused.

Same issue here running iOS 16.0.2 on a real iPhone 12. In my case though there are only complaints and no real errors.

Having this same error message generated on my iOS 16.0.2. No effect on the app but don't know what caused this. I ensured the spoken content is on and the voices are downloaded.
