Why does this SwiftUI Picker code not work?

Question

Xcode: 11.2.1

The code below is for a simple form with two components; a Picker (to select a letter) and a Text (to display the selected letter). The code compiles

Answer 1

ForEach types inside Picker should be aligned with selection type.

Here is a corrected code that should work for you:

@State private var letter = ""
private let letters = ["Alpha", "Bravo", "Charlie"]

var body: some View {
    NavigationView {
        Form {
            Picker("Select a letter", selection: $letter) {
                ForEach(letters, id: \.self) { option in
                    Text(option)
                }
            }
            Text("Selected letter: \(letter)")
        }
        .navigationBarTitle("Main Menu")
    }
}
