Have the requirements to support swipe to dismiss from a quick-look view controller changed in iOS18? I am noticing that my app no longer supports gestural dismissal in an iOS18 build.
Not this is a QLPreviewController presented from a UIViewController presented in a SwiftUI view hierarchy as part of a ViewControllerRepresentable.
Workaround: Assign a delegate and implement:
func previewController(_ controller: QLPreviewController, transitionViewFor item: QLPreviewItem) -> UIView? {
UIView()
}
If anyone at Apple would like this fixed, please file a radar.
Thanks @J0hn but I noticed this creates a little white view during dismissal. I've done this for now so when you drag you still see the preview's view.
func previewController(_ controller: QLPreviewController, transitionViewFor item: any QLPreviewItem) -> UIView? {
if controller.isBeingDismissed {
return controller.view
}
return nil
}
