iOS get physical screen size programmatically?

Question

Is this possible? I want the number of inches, not the number of pixels. I know it is approximately 160 ppi. But not exactly.

Answer 1

note: screen rotation matters here

extension UIScreen {
    var physicalSize:CGSize {
        return CGSize(width: bounds.width*scale, height: bounds.height*scale)
    }
}

using:

print(UIScreen.main.physicalSize)
