In Swift, how to determine the physical size of a device screen?

Question

I am adding views programatically. For example, I have a scrollView as a top-bar menu, I set its height to 60. (I am already using auto layout for placing these views)

This top-bar menu looks alright visually in an iPad. However, in an iPhone, it's kind of occupying too much space. Therefore, I am thinking to change the height to 45 for an iPhone.

What's the way to get the physical size of the screen? (not screen resolution) So I can make the height proportional to the physical size?

Answer 1

You can get this information accessing UIScreen singleton.

To get size use UIScreen.main.nativeBounds. Also you can get scale coefficient of screen UIScreen.main.nativeScale.
