.underline()

The .underline() view modifier in SwiftUI applies an underline style to text characters in a View.

Text("This text will be underlined")
    .underline()

The .underline() modifier is applied to all characters within the Text (which conforms to the View protocol).

The following example creates some underlined text:

var body: some View {
    Text("Underlined text")
        .underline()
    }

In the above example, the .underline() modifier is called on the Text view. This applies an underlined style to all characters within the Text.
