// Though we have Player struct import from Bridge Header

let player = Player()

print(player.name)

let otherName = ("W", "a", "l", "k", "e", "r")
let playerName: String = String.fromTuple(tuple: otherName)

print(playerName)

Player.h

// Player.h
type struct Player {
  char name[23];
  int level;
} Player;
