NSDictionary - cannot call "init"

This is the code

let dictionary = NSDictionary(objects: [user.username, image], forKeys: ["username", "image"])

      

        
        
        
      

    

I am getting the error

Can't call "init" with argument list type (objects: $ T3, forKeys: $ T7)

Additional code to show how username and images are generated

let users = objects

                        for userId in self.arrayUserIds
                        {
                            let user = self.getUserFromUserId(userId as String, arrayUsers: users)

                            self.arrayUserFriends.addObject(user)

                            var query = PFQuery(className: "UserPhoto")
                            query.whereKey("user", equalTo: user)

                            query.findObjectsInBackgroundWithBlock{
                                (NSArray objects, NSError error) -> Void in

                                if(objects.count != 0)
                                {
                                    let object = objects[objects.count - 1] as PFObject
                                    let theImage = object["imageData"] as PFFile

                                    let imageData:NSData    = theImage.getData()
                                    let image               = UIImage(data: imageData)


                                    let dictionary = NSDictionary(objects: [user.username, image], forKeys: ["username", "image"])
                                    self.arrayFriends.addObject(dictionary)

                                    self.chatTable.reloadData()
                                }
                            }
                        }
