That generates an array of assorted action names, and selects archery as being the default. Now we will use the chosen activity within our UI making use of string interpolation – we will location the selected variable specifically inside strings.

The buttonStyle() modifier tells SwiftUI we wish this button to stick out, so you’ll see it look in a blue rectangle with white text.

the struct – Meaning they belong site web to ContentView, as opposed to just remaining free of charge-floating variables inside our software.
