Answer 1

Method stringByTrimmingCharactersInSet returns a new string made by removing from both ends of the String characters contained in a given character set.

We can also just remove only whitespace, newline or both.

  let newString = textView.text.trimmingCharacters(in: .whitespacesAndNewlines)

Answer 2

You can try this :

let new = yourTextView.text.trimmingCharacters(in : .whitespacesAndNewlines)
