在运行时更改 iOS 13 中的根视图控制器

Question

I use switchRootViewController in this UIWindow extension to switch my root ViewController when the app shifts from register flow screens to Dashboard screen.

In iOS 13, this gives a blank screen. I've tried changing from keyWindow to windows.first as well. Still it is giving blank screen. Any idea how to fix this?

Note: I haven't added Scene delegate. My root view controller launches fine in the first launch. When I try to change it later on using that extension, then blank screen comes.

Try my answer from this post : How do I dismiss a rootViewController before presenting a new UITabBarController?

Just replace MyTabBarController with your DashboardViewController .
