I was able to set up my app so that a user can register with an email and password and was able to make a post but when I integrated the facebook login, I was not able to make any posts (writing to Firebase), I looked into permissions that might be necessary for those users but wasnt able to find anything. The following is my code for my posting to firebase

 @IBAction func handlePostButton(_ sender: Any) 

 guard let userProfile = UserService.currentUserProfile else return 


 //Firebase code
 //Lets make a reference to the database
 let postref = Database.database().reference().child("posts").childByAutoId() //This will assign this post a specific identifier that we can reference it by.
 //This is referencing the place where you write a post
 let postObject = [
 "author":[
 "uid": userProfile.uid,
 "photoURL": userProfile.photoURL.absoluteString,
 "username": userProfile.username
 ],
 "text": textView.text,
 "timestamp": [".sv": "timestamp"] //This is actually getting the time from Firebase, this is a server value.
 ] as [String:Any]
 postref.setValue(postObject, withCompletionBlock: Error, ref in
 if Error == nil 
 self.dismiss(animated: true, completion: nil)
 else 

 self.creatAlert(title: "Error", message: "Error making a Post!")
 
 )

not sure what else I should put up.
