NSCocoaErrorDomain

At WWDC17, new recording features were announced for WatchOS 4. And I've been trying to get a PCM array, but I was not successful.Currently I tried to use the following code.Check AudioSession: override func awake(withContext context: Any?) { super.awake(withContext: context) let recordingSession = AVAudioSession.sharedInstance() do { try recordingSession.setCategory(AVAudioSessionCategoryPlayAndRecord) try recordingSession.setActive(true) recordingSession.requestRecordPermission() { [unowned self] allowed in DispatchQueue.main.async { if allowed { self.recordingSessionSuccessfulPermission() } else { self.recordingSessionFailPermission() } } } } catch { self.recordingSessionFailPermission() } }Start Record: @IBAction func startRecordButton() { label.setText(start record) let audioEngine = AVAudioEngine.init() let inputNode = audioEngine.inputNode let format = inputNode.inputFormat(forBus: 0) inputNode.installTap(onBus: 0, bufferSize: 8000, format: format) { (buf, wheb) in self.label.setText(It is working) } a

I have downloaded Xcode 9 beta 3, renamed it as Xcode9b3.app and moved it to /Applications. When I run it, a popup appears telling me I need to install extra tools. Part way through the installation it crashes. I am running macOS Sierra 10.12.5.I'll paste the full crash report, but the bits that looks most relevant are:UNCAUGHT EXCEPTION (NSInternalInconsistencyException): Error getting value for key 'supportedClass' of extension 'Xcode.IDEKit.CocoaTouchIntegration.Navigable.PreviewItemGroup' in plug-in 'com.apple.dt.IDE.IDEInterfaceBuilderCocoaTouchIntegration'Error Domain=NSCocoaErrorDomain Code=3588 dlopen(/Applications/Xcode9b3.app/Contents/PlugIns/IDEInterfaceBuilderCocoaTouchIntegration.framework/IDEInterfaceBuilderCocoaTouchIntegration, 265): Symbol not found: _SimAudioHostUseSystemDefaultDeviceUIDn Referenced from: /Applications/Xcode9b3.app/Contents/PlugIns/IDEInterfaceBuilderCocoaTouchIntegration.framework/Versions/A/../../../../Developer/Library/PrivateFrameworks/SimulatorKit.framework/Ver

I'm adapting my App (OSX, XCode 8.3) to sandbox.I've created the entitlements for the app.I'm locked at the first step of writing a file.In the basic version, I do so :IBAction is called by menu item @IBAction func newDossier(_ sender: NSMenuItem) { let savePanel = NSSavePanel() savePanel.title = List file savePanel.prompt = Create let fileManager = FileManager.default savePanel.begin() { (result) -> Void in if (result == NSFileHandlingPanelOKButton) { let fileWithExtensionURL = savePanel.url!.appendingPathExtension(xxxx) // I call the file Theleme and select Desktop as location if fileManager.fileExists(atPath: fileWithExtensionURL.path) { // warning that file did exist already } else { // fileWithExtensionURL is written to a global var globalURL = fileWithExtensionURL let _ = writeAFile } } } } func writeAFile() -> Bool { let url = globalURL // fileWithExtensionURL from the NSSavePanel, stored in a global let data = NSMutableData() let archiver = NSKeyedArchiver(forWritingWith: data) // Call archiver.

After updating to iOS11 beta 5 initializing an UIDocumentPickerViewController:let documentPicker = UIDocumentPickerViewController(documentTypes: [public.zip-archive], in: .import)shows these messages at runtime:[DocumentManager] Failed to get the remote browser View Controller with error (Error Domain=NSCocoaErrorDomain Code=4097 connection from pid 508 UserInfo={NSDebugDescription=connection from pid 508}) [DocumentManager] Failed to get the service proxy object with error Error Domain=NSCocoaErrorDomain Code=4099 The connection from pid 508 was invalidated.

integrate the app extension by using the guides from: https://developer.apple.com/documentation/callkit ;once the extension is created on our app and linked to the target and with the proper development certificate, we run the app;on system settings when we try to activate the extension we get the following error:Error Enabling Extension - An error ocurred while attempting to enable <Extension name>. On Call Blocking & Identification system settings.these are the system logs related to such error:Aug 11 16:08:07 iPhone Preferences(UIKit)[281] <Notice>: activate generator <_UIFeedbackImpactBehavior: 0x174110a10: prepared=1> with style: TurnOn; activationCount: 1 -> 0; styleActivationCount: 1 -> 0 Aug 11 16:08:07 iPhone Preferences(UIKit)[281] <Notice>: feedback engine <_UIFeedbackHapticEngine: 0x1744c4a60: state=0, numberOfClients=1, prewarmCount=0, _isSuspended=0> state changed: Inactive -> Activating Aug 11 16:08:07 iPhone Preferences(AudioToolbox)[281] <Notice&g

I'm trying to open a file for writing. I can get the URL but the FileHandle always comes back nil. Any idea why this won't work?let fileURL = try FileManager.default.url(for: .documentDirectory, in: .userDomainMask, appropriateFor: nil, create: false).appendingPathComponent(test.tag) let file: FileHandle? = try FileHandle(forWritingTo: fileURL)file always comes back as nil. I get this error:Error Domain=NSCocoaErrorDomain Code=4 The file “test.tag” doesn’t exist. UserInfo={NSFilePath=/var/mobile/Containers/Data/Application/0D688141-D9C2-4CD0-849F-A2CBC69E34CD/Documents/test.tag, NSUnderlyingError=0x1c465d760 {Error Domain=NSPOSIXErrorDomain Code=2 No such file or directory}}Isn't the FileHandle call supposed to create the file? How else do you do it? The only other create file I can find is one that creates a file when you already have the complete contents to provide at the start, and I don't.Thanks!
