How to stack modifiers to create more advanced effects

Updated for Xcode 15

Each modifier you add to a view adjusts whatever came before it, and you’re able to repeat modifiers more than once.

For example, we could add padding and a background color around a text view, then add some more padding and a different background color, then add some more padding and a third background color, all to make a particular effect:

Text("Forecast: Sun")
    .font(.largeTitle)
    .foregroundStyle(.white)
    .padding()
    .background(.red)
    .padding()
    .background(.orange)
    .padding()
    .background(.yellow)

Download this as an Xcode project

The text “Forecast: Sun” in white on concentric rectangles colored (from inside outwards) red, orange, and yellow.

This is particularly useful for things like shadows, where you can create stronger shadow effects by repeating them as often as you need.
