How to make TextField uppercase or lowercase using textCase()

SwiftUI’s TextField view normally lets users write their text in whatever case they want, but if you want to control that you can force either uppercase or lowercase text using the textCase() modifier.

For example, this asks users to enter their name and uppercases every letter:

struct ContentView: View {
    @State private var name = "Paul"

    var body: some View {
        TextField("Shout your name at me", text: $name)
            .textFieldStyle(RoundedBorderTextFieldStyle())
            .textCase(.uppercase)
            .padding(.horizontal)
    }
}
