I can't custom the WelcomeScreenViewController to add BlurView and custom BackgroundView.

[Antoniochavez17]

I really love your project, but I have faced issues. When I tried to add this code.

extension WelcomeScreenViewController: UIViewController{
    
    
}

And I can pulling the WelcomeScreenViewController from your project files to doing in the UIView BackgroundView. I just want to custom or add anythings withview.addsubview()

but I faced xcode errors say Inheritance from non-protocol type 'UIViewController'

For example:

View.alpha = 0.5
View.backgroundColor = UIColor.black

Then I add UIVisualEffectView

then

view.addSubview(blurEffectView)

something like that.
This is my own code, but simple like this.

Let me know. Thank you so much.
