ios - 在将其解析为 JSON 文件 Swift 后声明类型

Question

现在我有一个从 Pearson 的 API 获得的 JSON 输出:

Optional(<__NSCFArray 0x7f9b7601a910>(
{
    datasets =     (
        laad3,
        dictionary
    );
    headword = theoretically;
    id = cs1tNTvYvg;
    "part_of_speech" = adverb;
    senses =     (
                {
            definition = "used to say that something could happen, but it is extremely unlikely";
            examples =             (
                                {
                    text = "It\U2019s theoretically possible for everyone in the class to get 100%.";
                }
            );
        }
    );
    url = "/v2/dictionaries/entries/cs1tNTvYvg";
},
{
    datasets =     (
        laad3,
        dictionary
    );
    headword = theoretical;
    id = cs1tNTpDbZ;
    "part_of_speech" = adjective;
    senses =     (
                {
            definition = "relating to or based on ideas, especially scientific ideas, rather than practical work or experience";
            examples =             (
                                {
                    text = "theoretical research";
                }
            );
        }
    );
    url = "/v2/dictionaries/entries/cs1tNTpDbZ";
})

并假设上面的输出存储到:

let results = parsedResult!["results"]

XCode 说下标的使用不明确，谷歌搜索后似乎我必须转换结果类型才能继续。我必须将 results 的类型转换为例如[[String:String]]?

旁注:有谁知道为什么 Xcode 提示在我的 iPhone6 和 iOS 9.3 上选择运行目标时下标使用不明确，但在模拟器中运行时却没有(也在 iPhone6 和 iOS9.3 上) ？

Answer 1

我不明白这个问题的深层原因。但从 XCode 7.3(或者更确切地说是 Swift 2.2)开始，编译器现在会在使用 NSDictionary 时提示下标的使用不明确。

要避免该错误，请将 NSDictionary 实例转换为 [String: AnyObject] 并将 NSArray 实例转换为 [AnyObject].
