ios - 转换此代码时我哪里出错了，因此它不会将变量放入数组中？

Question

以下代码片段:

if let dict = json?["Stats"] as? [String:AnyObject] {

       if let newdict = dict["biggestWin"] as? [[String : AnyObject]] {
       self.bigWinPlayer1Goals = newdict.flatMap { $0["player1_goals"] as! String!}
        print (self.bigWinPlayer1Goals)
}

输出:

["1"]

但是，1 包含在一个数组中——这是我不想要的。所以我重写了代码:

if let newdict = dict["biggestWin"] as? [String : AnyObject] {
        let bigWinPlayer1Goals = newdict ["player1_goals"] as? String
        print (bigWinPlayer1Goals!)
 }

但是这不起作用，并且不输出任何内容。

我哪里错了？

这是有问题的数组:

["Stats": {
biggestWin =     (
            {
        "player1_goals" = 1;
        "player2_goals" = 2;
    }
);
goalDifference = "-17";
goalsConceded = 32;
goalsScored = 15;
totalDraws = 3;
totalLosses = 10;
totalWins = 1;
winPercentage = "7.14%";
}]

我希望能够将 player1_goals 和 player2_goals 存储在两个单独的变量中。

dict["biggestWin"] 返回的值是 [String : AnyObject]] 类型，即 AnyObject 的 Array .

if let data = dict["biggestWin"] as? [[String : AnyObject]] {
    let newdict = data.first!
    let bigWinPlayer1Goals = newdict ["player1_goals"] as? String
    print (bigWinPlayer1Goals!)
}
