SwiftUI: ScrollView clipping

Problem

Some built-in view modifiers like .shadow do not introduce any additional padding that would increase the intrinsic size of the view.
This can cause problems when views are placed within UIKit hierarchies that enable .clipsToBounds.
This is the case with ScrollView, which internally uses a UIScrollView.

Solution

>= iOS 17

Use scrollClipDisabled(_:)

< iOS 17

Extending UIScrollView works, because .clipsToBounds is not read-only.

import UIKit

extension UIScrollView {
  open override var clipsToBounds: Bool {
    get { false }
    set { }
  }
}

One should be aware that this is applied globally.
