Question

I have a TableViewController, TableViewCell and a ViewController. I have a button in the TableViewCell and I want to present ViewController with presentViewController<

Answer 1

I had the same problem and found this code somewhere on stackoverflow, but I can't remember where so it's not my code but i'll present it here.
This is what I use when I want to display a view controller from anywhere, it gives some notice that keyWindow is disabled but it works fine.

extension UIApplication
{

    class func topViewController(_ base: UIViewController? = UIApplication.shared.keyWindow?.rootViewController) -> UIViewController?
    {
        if let nav = base as? UINavigationController
        {
            let top = topViewController(nav.visibleViewController)
            return top
        }

        if let tab = base as? UITabBarController
        {
            if let selected = tab.selectedViewController
            {
                let top = topViewController(selected)
                return top
            }
        }

        if let presented = base?.presentedViewController
        {
            let top = topViewController(presented)
            return top
        }
        return base
    }
}

And you can use it anywhere, in my case I used:

func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
    let storyboard = UIStoryboard(name: "Main", bundle: Bundle.main)
    let vc = storyboard.instantiateViewController(withIdentifier: "WeekViewController")
    UIApplication.topViewController()?.navigationController?.show(vc, sender: nil)
}
