Swift 4 Textview goes to bottom of textview when press return key
Clash Royale CLAN TAG#URR8PPP Swift 4 Textview goes to bottom of textview when press return key
When I press return button when editing my textview, it makes a new line where I currently am editing the textview and it automatically goes to the bottom of the textview text. I think it is because I am using Firebase to keep the textview in realtime text so it can update on all devices. When i remove the observer in the following code, it works like its supposed to:
override func viewDidLoad()
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
ref = Database.database().reference()
textView.delegate = self
ref.child("Notes").observe(.value, with: (snapshot) in
let note = snapshot.value as? [String : String]
self.textView.text = note!["note"]
)
I also have this code to update the database with the text in the texview:
func textViewDidChange(_ textView: UITextView) //Fires when the textview text changes
print(textView.text)
self.ref.child("Notes/note").setValue(textView.text)
I think i am having a problem because it gets the text from the database and sets a new copy of the text into the textview how can i solve this problem?
I am trying to make a realtime notes app so it would great if i can figure this out by sending each character to the database so that different users can edit the same document

Maybe you should avoid setting the text view's
text property if the value of note["note"] is the same as the current value.– rmaddy

text
note["note"]

Do you really want to update Firebase for every character typed into the text view? Why not wait until the text view loses focus?
