How to add a placeholder to a TextField

Paul Hudson    @twostraws   

Fully updated for Xcode 11.1

SwiftUI’s TextField supports placeholder text just like UITextField did – gray text that is shown in the text field when it’s empty, either giving uses a prompt (“Enter your password”) or showing some example data.

To set a placeholder, pass it in as part of the initializer for your text field, like this:

struct ContentView: View {
    @State private var emailAddress = ""

    var body: some View {
        TextField("johnnyappleseed@apple.com", text: $emailAddress)
            .textFieldStyle(RoundedBorderTextFieldStyle())
            .padding()
    }
}

That will show “johnnyappleseed@apple.com” in the text field while it’s empty, but as soon as the user types something in there it disappears.
