Swift 3:

let start  = sender.beginningOfDocument
let end = sender.endOfDocument
let range = sender.textRange(from: start, to: end)!

let trimmedText = sender.text(in: range)
sender.replace(range, withText: "new text")

I got it.

let start: UITextPosition  = self.textInput.beginningOfDocument
let end: UITextPosition = self.textInput.endOfDocument
let range: UITextRange = textInput!.textRangeFromPosition(start!, toPosition: end!)!
textInput!.textInRange(range!) // for get text
textInput.replaceRange(range!, withText: "some text") // to write text

import Foundation
import UIKit

public extension UITextInput {
    public var text: String {
        get { text(in: textRange(from: beginningOfDocument, to: endOfDocument)!) ?? "" }
        set(value) { replace(textRange(from: beginningOfDocument, to: endOfDocument)!, withText: value) }
    }
}

Your textInput variable is never declared properly. You might want to consider learning more general practices of Swift before asking specific questions.

Proper declaration of textInput would look like:

class A : UIViewController {
    var textInput: UITextInput

I am passing a textView or textField to this init(). They were initialising in other controllers. Can you help me how to use a UITextInput ? – Sujisha Os Oct 28 '15 at 17:54
Why not use a `UITextField` and get the text with `textInput.text`? – Andrew Brooke Oct 28 '15 at 18:05
