SwiftUI Button tap only on text portion

The proper solution is to use the .contentShape() API.

Button(action: action) {
  HStack {
    Spacer()
    Text("My button")
    Spacer()
  }
}
.contentShape(Rectangle())

You can change the provided shape to match the shape of your button; if your button is a RoundedRectangle, you can provide that instead.
