Reply to PDFKit PDFPage.characterBounds(at:) returns incorrect coordinates iOS 18 beta 4
iOS 18.3 beta 3 (22D5055b5) does not fix the issue! I have tested text extraction through the lower level CoreGraphics framework with CGPDFScannerScan(). It returns the same correct text results on iOS 17 and iOS 18! Seems this is a PDFKit bug, not a lower-level CoreGraphics bug. How can I help to further analyse this PDFKit issue and eventually get this Apple framework bug fixed!?

Reply to iOS 18.x PDFKit Page.string and Page.attributedString return some text way out of oder
Thank you for your detailed reply and suggestion to separate into two feedbacks! I will split/update the feedback as soon as I can manage. FYI, I have filed the Page.characterBounds(at:) bug under FB14843671 already in August '24 during the beta cycle. But have so far seen neither any Apple reaction, bug confirmation nor a bug fix. That made me wonder that I missed something or even reported a non-bug. But looking into the issue again in more detail I have to reconfirm my view that there is an Apple framework issue. This means that with iOS 18 release the large majority of the users of my app is completely stripped of a core feature, i.e. importing, semantically analysing and parsing PDF scripts (of actors) because of that bug. Really tough to cope with.

The app breaking PDFKit bug is still not fixed! Soon there is end of year but still not fixed! I really do not understand why an established Apple framework does not get fixed during the beta cycle. Even less so that it is not yet fixed while we are into the second point-update of the new OS. During the iOS 17 beta cycle I had reported the same bug and it got fixed within two weeks. What a surprisingly bad developer experience.

Reply to Random crash from AVFAudio library
It seems I do get the same crash on my iOS code. I could not reproduce it, but get between 1 and 4 crashes from every 200 user sessions. Any hints on how to solve this issue would be highly appreciated. Here is my code (very similar to code shown above): private func transcribe() { guard let recognizer, recognizer.isAvailable else { print("--- SpeechRec.transcribe - SpeechRecognizer TRANSCRIBE ERROR: \(RecognizerError.recognizerIsUnavailable)") return } do { if let audioEngine { let request = SFSpeechAudioBufferRecognitionRequest() request.shouldReportPartialResults = true request.requiresOnDeviceRecognition = false // might fix speechRec error 1101 in console let audioSession = AVAudioSession.sharedInstance() try audioSession.setCategory(.playAndRecord, mode: .measurement, policy: .default, options: .duckOthers) try audioSession.setActive(true, options: .notifyOthersOnDeactivation) let inputNode = audioEngine.inputNode let recordingFormat = inputNode.outputFormat(forBus: 0) inputNode.installTap(onBus: 0, bufferSize: 1024, format: recordingFormat) { (buffer: AVAudioPCMBuffer, _) in request.append(buffer) } try audioEngine.start() self.recognitionTask = recognizer.recognitionTask(with: request, delegate: self) } else { let (audioEngine, request) = try Self.prepareEngine() self.audioEngine = audioEngine self.request = request self.recognitionTask = recognizer.recognitionTask(with: request, delegate: self) } } catch { Logger.audio.error("--- SpeechRec.transcribe - SpeechRecognizer AudioSession/AudioEngine ERROR: \(error)") self.reset() } } This is the backtrace that the Organizer shows in Xcode: Last Exception Backtrace (0) #0 (null) in __exceptionPreprocess () #1 (null) in objc_exception_throw () #2 (null) in +[NSException raise:format:arguments:] () #3 (null) in AVAE_RaiseException(NSString*, ...)
