TextField

Part of the Introduction to SwiftUI section of Coddy's Swift journey. Lesson 24 of 50.

A TextField lets the user type. It needs a placeholder and a binding to a String state:

@State private var name = ""

var body: some View {
    VStack {
        TextField("Your name", text: $name)
        Text("Hello, \(name)!")
    }
}

The $ in $name turns the state into a binding: a two-way connection. The field shows the value of name, and every key the user types writes back into it. The text below reads the same state, so it updates on each keystroke.

.textFieldStyle(.roundedBorder) draws the familiar rounded box around the field.

Challenge

Easy

Greet the user by name. Add a TextField with the placeholder Your name bound to name, and give it the identifier name. Keep the greeting text, which should read Hello, Ada! after the user types Ada.
