How to get device width and height?

Question

In Objective-C we can get device width and height by using following code :

CGRect sizeRect = [UIScreen mainScreen].applicationFrame
float width = sizeRect.         


        

Answer 1

var sizeRect = UIScreen.mainScreen().applicationFrame
var width    = sizeRect.size.width
var height   = sizeRect.size.height

Exactly like this, tested it also.

Answer 2

This works great for Xcode 12

func iPhoneScreenSizes() {
        let height = UIScreen.main.bounds.size.height
        switch height {
        case 480.0:
            print("iPhone 3,4")
        case 568.0:
            print("iPhone 5 | iPod touch(7th gen)")
        case 667.0:
            print("iPhone 6 | iPhone SE(2nd gen) | iPhone 8")
        case 736.0:
            print("iPhone 6+ | iPhone 8+")
        case 812.0:
            print("iPhone X | iPhone XS | iPhone 11 Pro")
        case 896.0:
            print("iPhone XR | iPhone XS Max | iPhone 11 | iPhone 11 Pro Max")
        default:
            print("not an iPhone")
        }
    }

Answer 3

Since you're looking for the device screen size the simplest way is:

let screenSize = UIScreen.mainScreen().bounds.size
let width = screenSize.width
let height = screenSize.height

Answer 4

I haven't tried but it should be..

var bounds = UIScreen.main.bounds
var width = bounds.size.width
var height = bounds.size.height

Answer 5

If you want to use it in your code. Here you go.

func iPhoneScreenSizes() {
    let bounds = UIScreen.main.bounds
    let height = bounds.size.height

    switch height {
    case 480.0:
        print("iPhone 3,4")
    case 568.0:
        print("iPhone 5")
    case 667.0:
        print("iPhone 6")
    case 736.0:
        print("iPhone 6+")
    case 812.0:
        print("iPhone X")
        print("iPhone XS")
        break
    case 896.0:
        print("iPhone XR")
        print("iPhone XS Max")
        break
    default:
        print("not an iPhone")

    }
}

Answer 6

While @Adam Smaka's answer was close, in Swift 3 it is the following:

let screenBounds = UIScreen.main.bounds
let width = screenBounds.width
let height = screenBounds.height
