When tapping a UIButton I present a view controller like this:
let vc = ViewController()
present(vc, animated: true, completion: nil)
Inside, I set a clear background with a visual effect view with a blur effect, like this:
view.backgroundColor = .clear
blurEffectView = UIVisualEffectView(effect: UIBlurEffect(style: .regular))
//autolayout constraints for the blurEffectView
view.addSubview(blurEffectView)
But the background remains full white in iOS 26.
How can I bring the blur+transparency back like in iOS 18? What am I doing wrong?
