@anujtiwari I think u should disable iqmanger in this controller and use constraint something like this https://stackoverflow.com/questions/31356293/uitableview-and-uiview-with-keyboardwillshow/31356527#31356527 — Bhavin Bhadani, Apr 05 '18 at 12:39

Swift 5.0 :- Drag your UITextView in a contentView(UIView), Create IBOutlet of bottom constraint of contentView i.e bottomConstraint. After use the below code as mentioned and custom NavigationBar will also stick at top only textView will be just above keyboard.

 override func viewDidLoad() {
    super.viewDidLoad()
    let center: NotificationCenter = NotificationCenter.default
    center.addObserver(self, selector: #selector(Profile.keyboardWillShow(notification:)), name: NSNotification.Name.UIKeyboardWillShow, object: nil)
    center.addObserver(self, selector: #selector(Profile.keyboardWillHide(notification:)), name: NSNotification.Name.UIKeyboardWillHide, object: nil)
}

@objc func keyboardWillShow(notification: NSNotification){

let userInfo:NSDictionary = notification.userInfo! as NSDictionary
let keyboardSizeNow:CGSize = (userInfo.object(forKey: UIKeyboardFrameEndUserInfoKey)! as AnyObject).cgRectValue.size
UIView.animate(withDuration: 0.2, animations: { () -> Void in
    self.bottomConstraint.constant = keyboardSizeNow.height - 49
    self.view.layoutIfNeeded()
 })
}

@objc func keyboardWillHide(notification: NSNotification){
    UIView.animate(withDuration: 0.2, animations: { () -> Void in
        self.bottomConstraint.constant = 0
        self.view.layoutIfNeeded()
    })
}

you can implement keyboardWillShow and keyboardWillHide method in similar way

func keyboardWillShow(notification: NSNotification) {

        if let keyboardSize = (notification.userInfo?[UIKeyboardFrameEndUserInfoKey] as? NSValue)?.cgRectValue {
            buttonBottomConstraint.constant = keyboardSize.height
            UIView.animate(withDuration: 0.3, animations: {
                self.view.layoutIfNeeded()
            })
        }
    }
    func keyboardWillHide(notification: NSNotification) {
        if let _ = (notification.userInfo?[UIKeyboardFrameBeginUserInfoKey] as? NSValue)?.cgRectValue {
            bottomConstraint.constant = 0
            UIView.animate(withDuration: 0.3, animations: {
                self.view.layoutIfNeeded()
            })
        }
    }

also, don't forget to observe in viewDidLoad.
