json - 解析本地json文件

Question

我有这个 JSON 文件:

{
    "People" : [{
        {
            "Name": "Jack"
            "Age": 130,
            "Job": "Doctor",
        },
        {
            "Name": "Mark"
            "Age": 45,
            "Job": "Engineer",
        },
        {
            "Name": "Sarah"
            "Age": 27,
            "Job": "Designer",
        },

    }]
}

下面是我如何使用辅助函数解析它:

static func parseJson(file: String) -> [String: Any] {
        let jsonFile = Bundle.main.path(forResource: file, ofType: "json")
        let jsonData = NSData(contentsOfFile: jsonFile!)
        let jsonDictionary = try? JSONSerialization.jsonObject(with: jsonData! as Data, options: [])

        return jsonDictionary as! [String: Any] <-- Error
    }

然后当我尝试初始化它时:

let data = parseJson(file: "People")  as! [String: Any]
print(data["people"])

我收到这个错误:

fatal error: unexpectedly found nil while unwrapping an Optional value

我在这里做错了什么？我跟着这个tutorial by Apple

始终使用一些验证器来验证您的 JSON。

正确的JSON格式:

{
    "People" : [
        {
            "Name": "Jack",
            "Age": 130,
            "Job": "Doctor",
        },
        {
            "Name": "Mark",
            "Age": 45,
            "Job": "Engineer",
        },
        {
            "Name": "Sarah",
            "Age": 27,
            "Job": "Designer",

    }]
}
