     cell.textLabel?.text = player.name 
     cell.detailTextLabel?.text = player.game

您需要首先定义Player类型。你可能会想到这样的事情：

class PlayersViewController: UITableViewController { 

    var players: [Player] = [] 
    var xplayers: [XPlayer] = [] 

    // struct type of Player 
    struct Player { 
     var name : String = "" 
     var height : Int = 0 
    } 

    // OR 

    // tuple type of XPlayer 
    typealias XPlayer = (String, Int)  

    func someMethod() { 

     self.players.append(Player(name: "John Herbert", height: 160)) 

     // OR 

     self.xplayers.append(("John Herbert", 160)) 

    } 
}
