OK, let’s learn how we can put the theory of App Architecture into practice, by creating a simple data model for Bullseye.

Game.swift

We’re ready to add a file for our Game model.

struct Game {

}

struct Game {
  var target: Int = 37
}

  var score: Int = 0

  var round: Int = 1

ContentView.swift

So switch back to ContentView.swift, and scroll to the top.

@State private var game: Game = Game()

Text(String(game.target))

func points(sliderValue: Int) -> Int {
  return 999
}

Text(
  """
  The slider's value is \(roundedValue).
  You scored \(game.points(sliderValue: roundedValue)) points this round.
  """
)
