在 Swift (Xcode) 中为不同的屏幕尺寸创建约束

Question

I'm trying to make a Tic-Tac-Toe game and almost it's finished but I have a problem with UI and setting constraints for different screen sizes. for example, I have a UIView in the bottom of the screen that has height constraint equal to superView but with multiple under 1 and an under-zero constant value and it looks great in some screen sizes like iPhone (XS max - Xs - 8 - 8plus) but it's not looking good in iPhone (SE or 5s) how can I make or edit constraint just for these screen sizes (4 inches) (SE - 5S)??

NOTE: I know about size classes in Swift (compact Any) but this concept doesn't help me in this situation because of all screen sizes in portrait mode is same each other

The situation you've described is not really understandable, but for adjusting the layout for some screen sizes you can have outlets for some constraints, and change those values in your code if the screen size is small. You can get the screen size from UIScreen like this UIScreen.main.bounds.size.height

This is not an approach to apply all the time though. In general, you should try to layout your views in a way that it is not necessary. I am sure if you upload screenshots of your view on big and small screens, and a screenshot of how is your layout done and what constraints do you have, you will get more help.
