Finish a small iPhone app screen in SwiftUI

I already have a simple iPhone app started in SwiftUI, but I need help polishing one screen and making it feel finished. The main thing is to clean up the layout, fix a few small UI issues on different screen sizes, and make the buttons and spacing behave properly. This is a small job, not a full app build. It should be a good fit if you like quick, tidy mobile tasks and can work without a lot of hand-holding.
