Swift 3.1 - 无法获取Facebook好友ID

Question

我试图打印我的Facebook好友ID列表，但结果为空。有任何想法吗？

FBSDKGraphRequest(graphPath:"me/friends", parameters:["fields": "id"]).start{(connection, result, err)in 

     if err != nil{ 
      print("errorGraph") 
      return 
     } 

     else{ 
      guard let data = result as? [String:Any] else { return } 
      let fbid = data["id"] 

      print("friendID:", fbid ?? "") 



     }}

这工作：

var faceFriendIDs:Array<Any> = [] 


FBSDKGraphRequest(graphPath:"me/friends", parameters:["fields":"id"]).start{(connection, result, error)in 

     let resultDict = result as! NSDictionary 
     let data:NSArray = resultDict.object(forKey: "data") as! NSArray 

     for i in 0..<(data.count){ 
      let valueDict:NSDictionary = data[i] as! NSDictionary 
      let id = valueDict.object(forKey: "id") as! String 
      self.faceFriendIDs.append(id) 
     } 



     print(self.faceFriendIDs) 

    }
