Don't use SafeArea in iOS

[AdrKacz]

Describe the bug
In iOS, UI clashes with phone features (rounded corners). Need to use some kind of safe area to draw the scanner.

To Reproduce
Steps to reproduce the behavior:

1. Go to '...'
2. Click on '....'
3. Scroll down to '....'
4. See error

Expected behavior
I expect the button to be in a area where the user can tap.

Screenshots
Can't be seen in a screenshot as the OS remove the rounded corners when you screenshot your screen.
