Swift: How to work with JSON when you don't know the name of the keys or the data type of the values

Question

I am having trouble wrapping my head around how to work with JSON where I will not know the name of the keys, or the data type of the values. Each time I get the data, the JSON will have different keys, and different data types. I have been trying to use generics to perform this action, but am not having much success.

I apologize, if others have already asked this question. I searched, but could not find a good explanation of how to achieve working with dynamic JSON in an SDK.

edited I had some code in my question that was not making much sense, I have removed it since it will probably not help others.

Answer 1

If you can't know the value types, how many values or the name of the properties the json contains why don't you just parse the json string into a dictionary and then iterate through the keys of this dictionary and look for what you want. Something like this :

if let dict = "Your json response".toDictionary(){
            for (key, value) in dict.enumerated(){
                //Do something with key || value
            }
        }

extension String {
    func toDictionary() -> [String: Any]? {
        return try? JSONSerialization.jsonObject(with: data(using: .utf8)! , options: []) as? [String: Any]
    }
}

使用Charles Web Debugging Proxy捕获您作为请求发送的内容以及您作为响应收到的内容，并且不要忘记按Shift + Command + P在其上启用 macOs 代理。
