如何使用“SwiftyJSON”将`JSON.Element`转换为`JSON`？

Question

我想在下面这样做。如何使用“SwiftyJSON”将JSON.Element转换为JSON？

public func convert() -> String? {
    let json :JSON = ["Animals" : ["dog","cat"], "Shop":"Tokyo"]
    let animals = json["Animals"]
    let repezentativeAnimal = animals.first
    repezentativeAnimal!["Shop"] = json["Shop"] // Value of tuple type 'JSON.Element' (aka '(String, JSON)') has no member 'subscript'

    // I want to return String below
    //  ["dog":"---", "Shop":"Tokyo"]
    return repezentativeAnimal.rawString() // error : Value of type 'JSON.Element?' (aka 'Optional<(String, JSON)>') has no member 'rawString'
}
