How to let users pick options from a menu
Updated for Xcode 12.5
SwiftUI’s Picker view has a dedicated style called MenuPickerStyle that shows a popup menu of its options, with the label for the picker being shown as a tappable button. The menu itself will automatically show a checkmark next to the currently selected option, and can display upwards or downwards depending on the position of the picker on-screen.
To demonstrate this, we could make a small menu button to let the user select a paint color:
struct ContentView: View {
@State private var selection = "Red"
let colors = ["Red", "Green", "Blue", "Black", "Tartan"]
var body: some View {
VStack {
Picker("Select a paint color", selection: $selection) {
ForEach(colors, id: \.self) {
Text($0)
}
}
.pickerStyle(MenuPickerStyle())
Text("Selected color: \(selection)")
}
}
}
