I have this warrning in Xcode console a minute after I send my app to a background:
Can’t endBackgroundTask: no background task exists with identifier 6, or it may have already been ended. Break in UIApplicationEndBackgroundTaskError() to debug.
Steps to reproduce:
- Create a new project in Xcode, install Fabric, TwitterCore and TwitterKit via CocoaPods.
- Install Log In With Twitter like in default code example from Fabric app.
- Run app in simulator and log in with Twitter account.
- Send app to background by going to Home screen, then wait for about one minute or less.
