Today Extension Failed to inherit CoreMedia permissions from

Question

I am trying to add a Today Extension in Swift to my Objective-C app. I keep getting this message in my debugger log: Failed to inherit CoreMedia permissions from 3005: (null). The number ex. 3005 is different every time. I am reading from NSUserDefaults from within the widget but I am reading/writing in the app itself. The only code in my TodayViewController is this the following:

override func viewDidLoad() {     super.viewDidLoad()      let formatter = NSNumberFormatter()     formatter.numberStyle = .CurrencyStyle     totalLabel.text = formatter.stringFromNumber(0)     coinsLabel.text = formatter.stringFromNumber(0)      formatter.maximumFractionDigits = 0     billsLabel.text = formatter.stringFromNumber(0)  }  func widgetMarginInsetsForProposedMarginInsets(defaultMarginInsets: UIEdgeInsets) -> UIEdgeInsets {     return UIEdgeInsetsMake(8.0, 16.0, 8.0, 16.0) }  func widgetPerformUpdateWithCompletionHandler(completionHandler: ((NCUpdateResult) -> Void)!) {     // Perform any setup necessary in order to update the view.      // If an error is encountered, use NCUpdateResult.Failed     // If there's no update required, use NCUpdateResult.NoData     // If there's an update, use NCUpdateResult.NewData      completionHandler(NCUpdateResult.NewData) } 

Answer 1

I believe the "Failed to inherit CoreMedia permissions from NNNN" warning is related to App Groups when you are creating an App Extension. Both your containing application and your app extension need to have the App Groups capability turned ON and using the same app group container ID (example: group.com.yourdomain.yourappname). App Groups are used to allow multiple apps access to shared containers and allow additional interprocess communication between apps.

First, click on Assets.xcassets

Second, click on Target Membership, check both your app and widget to allow widget access your resources.

After that, run your Widget again, it should now work fine.
