Too Long; Didn't Read
Often the UI of iOS applications is only designed for screens of one size. For example, iPhone X (375x812) or iPhone 13 (390x844), and then iOS developers make designs for screens of other sizes. With large screens, everything is simple. But placing the design of the iPhone X on the screen of the iPhone SE 2016 (1st gen.) is more difficult, some elements and indents have to be reduced manually.
