Programmatically change the height and width of a UIImageView Xcode Swift

Question

Hey for some reason I am struggling with trying to set the height and width of one of my image views  I want to set it so the height only goes for 20  of my screen  I know to regularly set it you can do things like  image    0 0 50 50   But I need the height to not be a static number  Something like image    0 0  frame height   0 2  50   Any suggestions
