Trying to trigger an update of a collectionview through push notifications.
Therefore I am working in AppDelegate.swift - Everything fails with error message: Thread 1: Fatal error: Unexpectedly found nil while unwrapping an Optional value
Even tried to reload the view, to no avail?
It works fine ordinarily, if I press the button assigned to the same function which loads the data, just nothing works within AppDelegate, is this intended behaviour ? If so, how are you supposed to dynamically update using push notifications?
Can anyone help, please ?
