如何存储FB graph API公共档案信息

Question

我很难将个人资料详细信息（名称，电子邮件个人资料图片和ID）的Facebook图形API响应存储到变量中，以后可以创建到对象中。我收到此错误

Value of type 'Any?' has no member 'dictionaryValue'

这是我的方法

func getUseProfile() {
    let graphRequest : GraphRequest = GraphRequest(graphPath: "/me", parameters: ["fields":"id, email, name, picture.width(480).height(480)"], httpMethod: .get)

    graphRequest.start(completionHandler: { (connection, result, error) -> Void in

        if error != nil {
            print("Error took place: \(String(describing: error))")
        }
        else {

            print("Print entire fetched result: \(String(describing: result))")
            print("Print id: \(String(describing: "id"))")

            if let responseDictionary = result.dictionaryValue {
                let fbEmail = responseDictionary["email"] as? String
                print(fbEmail)
                let fbName = responseDictionary["name"] as? String
                print(fbName)
                let fbId = responseDictionary["id"] as? String
                print(fbId)
                if let picture = responseDictionary["picture"] as? NSDictionary {
                    if let data = picture["data"] as? NSDictionary{
                        if let profilePicture = data["url"] as? String {
                            print(profilePicture)
                }}}}
        }
    })
    }

典型图形API响应：

 ({
email = "test@gmail.com";
id = 2624827091891056;
name = "Test Test";
picture =     {
    data =         {
        height = 480;
        "is_silhouette" = 0;
        url = "https://platform-lookaside.fbsbx.com/platform/profilepic/? 
 asid=2624827091891056&height=480&width=480&ext=1572756671&hash=AeQLcrXR_f-mejoi";
        width = 480;
    };
 };
 })
