swift - 将字符串转换为 NSObject Swift 3

Question

有人可以帮我解决这个问题吗？我收到这个快速编译器错误:

'Cannot convert value of type 'String' to expected dictionary key type 'NSObject'

let orderParameters =

        ["customer": [     <- //Getting the error in this line
            "first_name": "Jon",
            "last_name":"Doe",
            "email": "john.doe@gmail.com"],
       "shipping": "free-shipping",
       "gateway": "dummy",
       "bill_to": [
            "first_name": "Jon",
            "last_name": "Doe",
            "address_1": "123 Sunny Street",
            "address_2": "Sunnycreek",
            "city": "Sunnyvale",
            "county": "California",
            "country": "US",
            "postcode": "CA94040",
            "phone": "18768509132"],
            "ship_to": "bill_to"
        ] as [NSObject: AnyObject]

我是否为“客户”参数插入as NSObject？

Answer 1

不要将写为[NSObject: AnyObject]，而将写为[AnyHashable: Any]。

这是 Swift 3 表达字典一般概念的方式。
