Has anybody successfully got an audio recording on real device? I've tryed using presentAudioRecorderControllerWithOutputURL but only get a WatchKitRecordingFailedError, and the interface dismissed immediately. If I set WKAudioRecorderControllerOptionsAutorecordKey to NO then the record interface dismissed after I pressed the record button. Please HELP!And here is my code: NSURL *directory = [NSURL fileURLWithPath:NSTemporaryDirectory()]; NSURL * outputURL = [directory URLByAppendingPathComponent:@temp.wav]; [self presentAudioRecorderControllerWithOutputURL:outputURL preset:WKAudioRecorderPresetNarrowBandSpeech options:@{WKAudioRecorderControllerOptionsActionTitleKey:@OK, WKAudioRecorderControllerOptionsMaximumDurationKey:@120, WKAudioRecorderControllerOptionsAutorecordKey:@0} completion:^(BOOL didSave, NSError * _Nullable error) { //so I got didSave=0 and error=Error Domain=com.apple.watchkit.errors Code=6 Recording failed. UserInfo={NSLocalizedDescription=Recording failed.} }];I've also tryed using a group

If I only have one product item in Apple Pay, how would I detect a total? My app is a donation platform, so I don't need to actually ship anything, but would like contact info. I have a number of errors that I have tried to figure out to debug to no avail. Any help is appreciated.Also I keep getting this error (this was the same as the sample code given from WWDC).This is in my BuyTicketViewController.swift file. if PKPaymentAuthorizationViewController.canMakePaymentsUsingNetworks(BuyTicketViewController.paymentNetworks) { let button = PKPaymentButton(type: .Buy, style,: .Black) button.addTarget(self, action: applePayButtonPressed, forControlEvents: .TouchUpInside) button.center = applePayView.center button.autoresizingMask = [.FlexibleLeftMargin, .FlexibleRightMarin] applePayView.addSubview(button) } }The error says 'expected declaration.'The sample says to use else (for traditional checkout). When I put that it, it breaks the rest of my code and I get lots of errors.line 8 - eror on MerchantIDline 9 - error

I have integrated microsoft's ADAL Library for iOS https://github.com/AzureAD/azure-activedirectory-library-for-objc.I authenticated the azure's proxy share point site and keep the app in idle state for more than an hour. After I activate the app and click on any hyper-link I get the following errorCannot add a new item in the keychain. Error code: -25243. Attributes: { acct = cHJhcGF0aWxAZXF1aW5peC5jb20; svce = MSOpenTech.ADAL.1|aHR0cHM6Ly9sb2dpbi5taWNyb3NvZnRvbmxpbmUuY29tLzcyYWRiMjcxLTJmYzctNGFmZS1hNWVlLTlkZTZhNTlmNmJmYg|CC3513A0-0E69-4B4D-97FC-DFB6C91EE132|YzczOWU0ZmItNTE1ZC00N2JhLWIzOGMtZTk2MjZjOGRhODAy; }.

Hello Swift expertsI have a question that I know you know the answer to. I am writing some classes to build and handle a binary tree node. I think I have completed the task but am kinda unhappy with an error I got and I dont know why it appears. Please check the following sample of code out that reproduces the error, you can use a playground in XCode. I extracted this code from my class and simplified it to reproduce the failuere, so it doesn't follow any logic:class BinaryTreeNode { var data = 0 var left: BinaryTreeNode? = nil var right: BinaryTreeNode? = nil init(value: Int) { self.data = value } func getLeftChild() -> BinaryTreeNode? { return self.left } } class BinaryTree { var root: BinaryTree? func delete(value: Int, inout at root: BinaryTreeNode?) { if root != nil { var aNode: BinaryTreeNode? = BinaryTreeNode(value: 123) var anotherNode: BinaryTreeNode? = BinaryTreeNode(value: 65) var aTuple = (current: aNode, parent: anotherNode) self.delete(45, at: &aTuple.current!.getLeftChild()) self.delete(

When my app is opened I subscribe for 2 record types when created and updated. One of the objects I can only add 1 at a time and are spaces out, and the other type can have groups of records saved/updated at once. I use the background notifications to update my core data database and update the UI if the app is opened. I turned on notification alerts to see which notifications my devices get. I am testing on 4 devices, a iPad Air iOS 8.4, iPad Mini iOS 8.4, iPhone 5 iOS 9 and iPhone 6 Plus on iOS 9. When I create a TV show record (1 saved at a time), each device got that 1 notification. If I mark a episode as watched in my app (mutliple can be added to CloudKit and updated) my iPad Air received only 1 notification for that, my iPad Mini received 2 notifications, and my iPhone 5 also received only 2 notifications. I saved 4 objects to the cloud though. Is there a limit to the amount of notifications are sent, and what would be the best way to handle this?

I would like to give away my app to a selected group. I do not want to pay for all of these, just give them away. It is a paid app and the cost is around $4 for each and I would like to give out around 100 apps for marketing purposes.Tobbeswim
