In my app I have: let utterance = AVSpeechUtterance(string: recognizedTextView.text) utterance.voice = AVSpeechSynthesisVoice(language: "zh-HK") utterance.rate = 0.3 synthesizer.speak(utterance) However, after I upgraded my iOS to 17.1.1 the speed doesn't get adjusted. I tried 0.01 and 0.3 for rate, and there is no difference.

Something weird is happening? As I tested this on all the simulators including the physical phone, the search bar renders fine. However, when I quit Xcode and open the application on the phone, the search bar would not render with the correct width. (It would be all bunched up. It's hard to debug because this program isn't visible in any of the simulators.) Part of the code: override func viewDidLoad() { super.viewDidLoad() initList() }     override func viewDidAppear(_ animated: Bool) {         super.viewDidAppear(animated)         initSearchController()     } func initSearchController() { searchController.loadViewIfNeeded()         searchController.searchResultsUpdater = self         searchController.searchBar.sizeToFit()         searchController.searchBar.frame.size.width = self.view.frame.size.width searchController.obscuresBackgroundDuringPresentation = false searchController.searchBar.enablesReturnKeyAutomatically = false searchController.searchBar.returnKeyType = UIReturnKeyType.search         searchController.isActive = false         searchController.searchBar.placeholder = "Search poetry, lyrics, arias ..."         searchController.definesPresentationContext = true         searchController.searchBar.delegate = self         navigationItem.searchController = searchController         navigationItem.hidesSearchBarWhenScrolling = false }

Is it possible to do so? If so, how?

I tried to change my code from let urlString = Bundle.main.path(forResource: "X", ofType: "mp3")! to let urlString = Bundle.main.path(forResource: "X", ofType: "caf")! after I already uploaded the file. But it throws a fatal error: Unexpectedly found nil while unwrapping an Optional value I double check the filename and it's correct. and the caf file does play.
