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

(Swift 3) Keep in mind that most width and height values will be based on device's current orientation. If you want a consistent value that is not based on rotation and offers results as if you were in a portrait-up rotation, give fixedCoordinateSpace a try:

let screenSize = UIScreen.main.fixedCoordinateSpace.bounds
