how to detect which textview is being edited swift - ios

Question

I've got two textviews on my view and I want them both to be editable.
But each one pertains to a different record in my database.
How would I be able to detect which textView is being edited?
Here is my code so far
func textViewDidChange(textView: UITextView) { //Handle the text changes here
if(textView.textAlignment == .Center){
PFUser.currentUser()!["bio"] = textView.text
PFUser.currentUser()!.saveInBackground()
}
else{
PFUser.currentUser()!["displayName"] = textView.text
PFUser.currentUser()!.saveInBackground()
}
}
What I'm currently doing is detecting if the view is right aligned or center aligned to be able to tell them apart.
This works but it's not ideal as I'd like to have both of them center aligned. But I'm unaware which field in the textView object would contain an ID or some method of identification as to which textView the function was called for.

As long as you have properties that refer to the two text views you can simply see which one was passed to your delegate and act accordingly:
func textViewDidChange(textView: UITextView) { //Handle the text changes here
guard let currentUser = PFUser.currentUser() else {
return
}
if (textView == self.bioTextView){
currentUser["bio"] = textView.text
currentUser.saveInBackground()
} else {
currentUser["displayName"] = textView.text
currentUser.saveInBackground()
}
}
