How to push a UIViewController from a modal UIView?

I have a modal UIView created like below but I am unable to find a way to push another UIViewController from the UIView. The view's parent UIViewController does have a UINavigationController. All the code attempts below fail. The UIView has a UICollectionView

parent UIViewController

let searchView = SearchView()

view.addSubview(searchView)

modal UIView

class SearchView: UIView,
              UICollectionViewDelegateFlowLayout,
              UICollectionViewDataSource {

var collectionView: UICollectionView!


 ----


func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {

    let mainStoryBoard = UIStoryboard(name: "Main", bundle: nil)

    let myViewController: MyViewController = mainStoryBoard.instantiateViewController(withIdentifier: “MyViewController") as! MyViewController

//      let currentController = self.getCurrentViewController()

//        currentController?.navigationController?.pushViewController(myViewController, animated: true)

// self.parentViewController.navigationController.pushViewController(myViewController, animated: true) 


    let vc = self.window?.rootViewController

    let navController = vc?.navigationController

    navController?.pushViewController(myViewController, animated: true)

You can create one instance property of type UIViewController with your SearchView. Now use this property to pushViewController. After that initialized it where you are creating instance of SearchView.

class SearchView: UIView,
          UICollectionViewDelegateFlowLayout,
          UICollectionViewDataSource {

     var collectionView: UICollectionView!
     var vc: UIViewController?


    func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {

        let mainStoryBoard = UIStoryboard(name: "Main", bundle: nil)

        let myViewController = mainStoryBoard.instantiateViewController(withIdentifier: "MyViewController") as! MyViewController
        vc?.navigationController?.pushViewController(myViewController, animated: true)

    }

Now where you are adding this SearchView as subview set the vc property of its to self.

let searchView = SearchView()
searchView.vc = self
view.addSubview(searchView)
