Okay. I think the most important thing is the type of a dictionary. The issue is rather with mapper, but switching it to [String: String] fixes the problem:

struct Post: Mappable {
    let args: [String: String]?
    let headers: [String: String]?
    let origin: String
    let url: String

    init(map: Mapper) throws {
        args = map.optionalFrom("args")
        headers = map.optionalFrom("headers")
        try origin = map.from("origin")
        try url = map.from("url")
    }
}

Let me know if it solves your issue 🌞

[thienhaole92]

If I switch to [String : String] I can not map dictionary to object if it has Number or somethings else

[sunshinejr]

Yes, but this is one of the few types that mapper supports. See this function. And this is the list of default convertibles.

As a workaround you could use NSDictionary? instead of [String: String].

please did you find a solution for this problem ? @thienhaole92
