After listening to the recording, the sound interface of the Apple Watch

Question

I am trying to record audio using Apple Watch using the presentAudioRecorderControllerWithOutputURL method.

I am using Xcode 7.0 beta 5, iOS9 beta, WatchOS 2 beta and Swift2.

It works great on an emulator. However, as soon as on the device itself, it crashes when the method is called.

Here is my current code:

 @IBAction func onClickSpeech() { let filePaths = NSSearchPathForDirectoriesInDomains( NSSearchPathDirectory.DocumentDirectory, NSSearchPathDomainMask.UserDomainMask, true) let documentDir = filePaths.first! let recSoundURL = documentDir + "/record.m4a" let nsUrl = NSURL.fileURLWithPath(recSoundURL) let audioOptions = [ WKAudioRecorderControllerOptionsActionTitleKey : "Recording title", WKAudioRecorderControllerOptionsAlwaysShowActionTitleKey : false, WKAudioRecorderControllerOptionsAutorecordKey: true, WKAudioRecorderControllerOptionsMaximumDurationKey: NSTimeInterval.infinity ] presentAudioRecorderControllerWithOutputURL( nsUrl, preset: WKAudioRecorderPreset.NarrowBandSpeech, options: audioOptions as [NSObject : AnyObject]) { (didSave, error) -> Void in print("didSave:\(didSave), error:\(error)") } } 

recSoundURL is a valid path.

The error I get in device logs is:

 Aug 18 16:42:12 Sennetts-AppleWatch mediaserverd[283] <Error>: 16:42:12.532 EXCEPTION: [0x1f1ac000] >va> 565: kAudioHardwareUnknownPropertyError: "AudioObjectHasProperty([goin/glob/0]) returned false."

Any idea would be greatly appreciated as I cannot understand this. Thanks.

Please see the code below (using the application group’s shared folder )

  @IBAction func recordAudio() { let fileName = "audioFile.wav" let fileManager = NSFileManager.defaultManager() let container = fileManager.containerURLForSecurityApplicationGroupIdentifier(Constants.kAppGroupId) self.saveUrl = container?.URLByAppendingPathComponent(fileName) let duration = NSTimeInterval(120) let recordOptions = [WKAudioRecorderControllerOptionsMaximumDurationKey : duration] presentAudioRecorderControllerWithOutputURL(self.saveUrl!, preset: .WideBandSpeech, options: recordOptions, completion: { saved, error in if let err = error { print(err.description) } if saved { // Write code to execute when audio file gets saved. } }) }
