How to do object alignment on screen in Swift app?

Question

iOS

Hello.
How to make an object (sprite) in the application under IOS displayed in the upper right corner of the screen. The problem is that the resolutions of different iPhones are different, so this sprite always goes beyond the screen for me.
I know how it can be done through the graphical editor in Xcode, but how through the code?
PS I work on Swift SpriteKit.

through constants
self.view.frame.size.height - 20
self.view.frame.size.wight - 20
coordinates that the element will be down from the top and side by 20 pixels
set the element needs coordinates
(obzh-s code but you understand the logic)
