The documentation for hightlightProperty(withKey:identifier:) describes the parameter "key" as the "Key of the property to highlight." I believe that refers to the CNKeyDescriptor, such as CNContactGivenNameKey, which can cast from a type CNKeyDescriptor to String. The documentation for identifier is "the value to highlight". I believe an example of that would be "John" as the given name. Am I correct about all this? In any case, I'm not able to highlight an email property when I use CNContactEmailAddresses as the key, and an actual email address as the identifier. I have also tried using the identifier property of CNLabeledValue, which is how an email address is stored. I can't find anything on the internet to explain this. I didn't even find a similar question, except my own question asking this exact same question about two months ago. Anyone have any idea or a good answer for this?

I don't see any current posts about the warning that says "PosterBoard quit unexpectedly." on my Mac. Older posts say this is an error generated by Xcode Simulator. I tried one of those solutions but I still see this warning coming up. I am also not using Simulator. I'm using an actual device - an iPhone 13 Pro Max running iOS 16.6. When I click on Reopen in that alert box telling me that warning message, I get a warning in an alert box with a picture of the Finder icon on it, and it says "You can’t open the application “PosterBoard.app” because this application is not supported on this Mac.". Anyone else have this problem and know what do do about it? Like fix it or get around it?

I'm able to get text to speech to audio file using the following code for iOS 12 iPhone 8 to create a car file: audioFile = try AVAudioFile( forWriting: saveToURL, settings: pcmBuffer.format.settings, commonFormat: .pcmFormatInt16, interleaved: false) where pcmBuffer.format.settings is: [AVAudioFileTypeKey: kAudioFileMP3Type, AVSampleRateKey: 48000, AVEncoderBitRateKey: 128000, AVNumberOfChannelsKey: 2, AVFormatIDKey: kAudioFormatLinearPCM] However, this code does not work when I run the app in iOS 18 on iPhone 13 Pro Max. The audio file is created, but it doesn't sound right. It has a lot of static and it seems the speech is very low pitch. Can anyone give me a hint or an answer?
