swift 3 facebook sdk获取好友列表

Question

我需要得到我所有朋友的名单:

我找到了这段代码:

var fbRequestFriends: FBSDKGraphRequest = FBSDKGraphRequest(graphPath: "/{friend-list-id}", parameters: [AnyHashable : Any]())

fbRequestFriends.start { (connection, result, error) in
    if error == nil && result != nil {
        print("Request Friends result : \(result!)")
    } else {
        print("Error \(error)")
    }
}

但作为回报我得到这个错误:

@CBroe是对的,这就是代码的样子

let params = ["fields": "id, first_name, last_name, name, email, picture"]

let graphRequest = FBSDKGraphRequest(graphPath: "/me/friends", parameters: params)
let connection = FBSDKGraphRequestConnection()
connection.add(graphRequest, completionHandler: { (connection, result, error) in       
    if error == nil {
        if let userData = result as? [String:Any] {
            print(userData)
        }
    } else {
        print("Error Getting Friends \(error)");
    }

})

connection.start()
