To Reproduce
Steps to reproduce the behavior:

1. Install App on Real Device (with fetch capabilities)
2. Wait 15min with App run on background
3. Background Task Never called/fired

Additional context

When running on Simulator I try simulate fetch background on XCode, and the event is fired/called OK
When I run the same on real device, the background never fired !

If it works in the Simulator, that's all you need to know that it works. Everything else is up to the OS. You will never get an event after exactly 15 min. It all depends on Apple's machine-learning algorithm which presumably depends upon the frequency of interaction with your app (how often, how long and when your app is interacted with).

There is nothing you can do but wait. It can take days before iOS begins regularly emitting 'fetch' events and there nothing you can do but wait patiently.

This issue has been posted dozens of times before.

If it works in the Simulator, you're done.
