Profilseite swift 3 Fehler

Question

Dies ist der Code, den ich für meine Profilseite erstellt habe, aber er hat einige Fehler, die ich anpassen möchte.

import UIKit 
import FirebaseStorage 
import FirebaseDatabase 
import FirebaseAuth 
import Firebase 


class ProfileClass: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate { 


    @IBOutlet weak var userImagePicker: RoundButton! 
    @IBOutlet weak var ProfilePicture: RoundImage! 
    @IBOutlet weak var usernameField: UITextField! 
    @IBOutlet weak var imageLoader: UIActivityIndicatorView! 


    var loggedInUser = AnyObject?() 
    var databaseRef = FIRDatabase.database().reference() 
    var storageRef = FIRStorage.storage().reference() 
    var imagePicker = UIImagePickerController() 


    override func viewDidLoad() { 
     super.viewDidLoad() 

     self.loggedInUser = FIRAuth.auth()?.currentUser 

     self.databaseRef.child("user_profile").child(self.loggedInUser!.uid).observeSingleEvent(of: FIRDataEventType(.Value) { (snapshot:FIRDataSnapshot) in 


      if(snapshot.value!["usernameField"] !== nil) { 

      self.usernameField.text = snapshot.value!["usernameField"] as? String 

      } 
      if(snapshot.value!["profile_pic"] !== nil) { 

      let databaseProfilePic = snapshot.value!["profile_pic"] 
      as! String 
       let data = NSData(contentsOfURL: NSURL(string: databaseProfilePic)!) 

       self.setProfilePicture(self.ProfilePicture,imageToSet:UIImage(data:data!)!) 

      }
