I stuck on the same issue in a sheet. Found a solution, it works well for me. https://stackoverflow.com/questions/56491881/move-textfield-up-when-the-keyboard-has-appeared-in-swiftui/60178361#60178361

I came across the same issue, but cannot solve it by adding .navigationViewStyle(.stack). Instead, I switched from NavigationView to NavigationStack and got the issue solved. PS. I am working on iOS 16+ and SwiftUI 5.7
