Instantiate ViewController crashing on iOS 13

Question

App is crashing because of instantiateViewController() and it seems to affect iOS 13 users only.

let homeTabBarController = storyboard?.instantiateViewController(identifier: "home") as! HomeTabBarController

HomeTabBarController is a subclass UITabBarController. If I use a subclass of ViewController it works perfectly fine.

Answer 1

It’s because viewController storyboard is maybe nil at that time, try this

var myViewController = UIStoryboard(name: "Main", bundle: nil).instantiateViewControllerWithIdentifier("myViewControllerIdentifier") as! ViewController
