I've noticed that throughout our app whenever we use the dictation button on the keyboard to enter text in a UITextView and then press done without saying anything the following two lines appear in our logs:
!!! _NSLayoutTreeGetBaselineOffsetForGlyphAtIndex invalid glyph index 0
Localizable string "SiriSpeechErrorDomain" not found in strings table "Error" of bundle CFBundle 0x15fd54b50 </System/Library/Frameworks/CoreFoundation.framework> (framework, loaded).
A search for "SiriSpeechErrorDomain" yielded 0 results on google. Where are these log messages coming from and is this indicative of a potential issue?
I did a quick check by breakpointing in the textViewDidChange: delegate function of the UITextView and I got the following result:
First call of function immediately after hitting "Done" without dictating text:
p textView.text
(NSString *) $9 = 0x0000000178258240 @"\U0000fffc"
Second call of function:
p textView.text
(NSString *) $10 = 0x0000000197305980 @""
