Using the Facebook API in Swift. "Application ID not found"?

I have filled in the keys in info.plist according to the Facebook tutorial, but when I try to execute my application the following exception message is displayed:

'InvalidOperationException', Reason: "Application ID not found. Add a string value with your application ID for key FacebookAppID to Info.plist or call [FBSDKSettings setAppID:]."

I just checked the App ID and it is correct and I really don't know the reason for this error. Can someone help me?
