How to insert line break at the end of specific line of UITextView

Question

I have UITextView with 10 lines and now I'm trying to insert line break at the end of 5th line. How is it possible?

Create an array by separating text with the line break. – El Tomato Jun 24 '20 at 07:08 — El Tomato, Jun 24 '20 at 07:08

Split the text into lines with components(separatedBy: .newlines)
Get the 5th line (at index 4!)
Get the range of the line in the text with range(of:)
Insert the line break at the upperBound index of the range.

Actually there is one whole text which looks like as 10 lines on simulator and when I'm trying to get components(separatedBy: .newlines) it only gets one whole text. – Lib3Rian Jun 24 '20 at 07:26
If there are no *physical* lines how do you know what the 5th line is? There is no way unless you know the partial string where the line break is supposed to be inserted. – vadian Jun 24 '20 at 07:30
Let's assume that 5th line is 5th line shown on simulator, is there a way to insert line break on that line without knowing partial string? – Lib3Rian Jun 24 '20 at 07:50

*On simulator* what? iPhone SE, 11 max, iPad something? No, you need to be able to identify the insertion location independent of the UI. – vadian Jun 24 '20 at 08:32

here is :

 let textview = UITextView()
        textview.frame = CGRect(x: 100, y: 100, width: 200, height: 200)
        textview.text = "djhgiruior seitii iuuiuy  yyt  yt tr dtre d grf hth yghj  jh u hu khku yi  hhhhh\nuiytuftftyftyfytf"
        textview.backgroundColor = .green
        self.view.addSubview(textview)

It will give new line after '\n' . So use this
