iPhone X safe area not working

Currently I’m working in this project where I need to resolve a UI issue for iPhone X. I did some reading that said developers can use safe areas in XIB and it will resolve the problem. So I did it, and the simulator looks fine, but not my real device.

All the UI Components are attached to safe area. But only iPhone X simulator looks okay. How do I resolve this?

Solution

I found out the answer. Apparently, it was because XIB files were cached. I have to clean the project and re-run it. And it's working perfectly.
