Usage

PreviewItem

The PreviewItem is a protocol that provides the behavior necessary for previewing. UIImage and AVPlayer have built-in implementations. It can also be customized.

extension String: PreviewItem {
    func makeViewController() async -> UIViewController {
        UIHostingController(rootView: Text(self))
    }
    
    func makeThumbnailViewController() -> UIViewController? {
        nil
    }
}

PreviewController

PreviewItem are displayed using PreviewController. PreviewController uses a PreviewControllerDataSource to retrieve PreviewItem.

let vc = PreviewController()
vc.delegate = self
vc.dataSource = self
present(vc, animated: true)

PreviewControllerDataSource

func numberOfPreviewItems(in controller: PreviewController) -> Int
func previewController(_ controller: PreviewController, previewItemAt index: Int) -> any PreviewItem

PreviewControllerDelegate

PreviewControllerDelegate supports animations on transitions.

func previewController(_ controller: PreviewController, transitionViewFor item: any PreviewItem) -> UIView?
