Note created	Feb 17, 2025

In SwiftUI views, is fairly common to use stateful properties to store and display data. However, that bifold functionality requires a special syntax, marking the variable with a dollar sign ($):

struct ContentView: View {
	@State private var name = ""
 
	var body: some View {
		Form {
			TextField("Enter your name", text: $name)  // two way
			Text("Hello, \(name)!")  // one way, we are only reading
		}
	}
}
