The linked documentation is generic and not helpful unfortunately.

I followed your suggestion: musicAlbumPredicate = #Predicate<MusicAlbum> { $0.artistName.localizedLowercase.contains(searchQuery.localizedLowercase) } It produced the following error messages: SwiftData/DataUtilities.swift:93: Fatal error: Couldn't find \MusicAlbum.artistName.localizedLowercase on MusicAlbum with fields [("artistName", \MusicAlbum.artistName, nil, nil), ("albumName", \MusicAlbum.albumName, nil, nil), ("songName", \MusicAlbum.songName, nil, nil), ("genre", \MusicAlbum.genre, nil, nil), ("rating", \MusicAlbum.rating, nil, nil), ("releaseDate", \MusicAlbum.releaseDate, nil, nil), ("coverPhotoFullFilename", \MusicAlbum.coverPhotoFullFilename, nil, nil)]

*** The problem in my case has been resolved *** I was declaring 'let speechSynthesizer = AVSpeechSynthesizer()' locally in my function in SwiftUI. It has been working until Xcode 14. I moved the 'let' to the top in my struct and made it a struct property. With no other code change, the problem is resolved.

I was hoping that Xcode 14.1 beta would solve this issue reported above, but unfortunately still the same errors. I have been getting these errors since Xcode 14.0 beta 3. Text-to-Voice is a critically important feature, but has been missing in Xcode 14 and now 14.1 beta. It works perfectly under iOS 15.6 and Xcode 13.x. Why is Apple not including this feature in Xcode 14?
