Hey everyone,

Some of the built-in iOS 14 widgets, like batteries or Siri Shortcuts, have a semi-transparent, blurred background to them, much like to new sidebars in macOS Big Sur. This has led me to two thoughs / questions.

Firstly, how would you make this? If you make an empty widget with, say, only a Text view, the widget gets a system background by default. Is there a way to override this?

And secondly, possibly more interesting: WidgetKit and widgets don't support integration with UIKit / AppKit, which means those widgets most likely aren't using a UIVisualEffectView / NSVisualEffectView for their backgrounds. Does this mean apple has a native SwiftUI blur view internally?

I'd love to read your thoughts on this.
