Swift 4 approach :-

private func fetchUserData() {
    let graphRequest = FBSDKGraphRequest(graphPath: "me", parameters: ["fields":"id, email, name, picture.width(480).height(480)"])
    graphRequest?.start(completionHandler: { (connection, result, error) in
        if error != nil {
            print("Error",error!.localizedDescription)
        }
        else{
            print(result!)
            let field = result! as? [String:Any]
            self.userNameLabel.text = field!["name"] as? String
            if let imageURL = ((field!["picture"] as? [String: Any])?["data"] as? [String: Any])?["url"] as? String {
                print(imageURL)
                let url = URL(string: imageURL)
                let data = NSData(contentsOf: url!)
                let image = UIImage(data: data! as Data)
                self.profileImageView.image = image
            }
        }
    })
}
