Question

I have 3 types of VC\'s , 1st Vc, 2nd VC is PageViewController with 3 pages(I added PageController to normal ViewController here), third o

Answer 1

navigationViewController is nil so I had to do the following:

(UIApplication.shared.keyWindow?.rootViewController as? UINavigationController)?.pushViewController(clvc, animated: true)


// Tap gestrure selector fuction
@objc func incomingCallsViewTapFunction(_ sender: UITapGestureRecognizer) {
    let clvc = self.storyboard?.instantiateViewController(withIdentifier: "FVC") as! FinalViewController
//        self.navigationController?.pushViewController(clvc, animated: false)

    (UIApplication.shared.keyWindow?.rootViewController as? UINavigationController)?.pushViewController(clvc, animated: true)

}
