registerFileRepresentation(for:visibility:openInPlace:loadHandler:)
Registers a file-backed representation for an item with item visibility, an open-in-place option, and a load handler.
Declaration
func registerFileRepresentation(for contentType: UTType, visibility: NSItemProviderRepresentationVisibility = .all, openInPlace: Bool = false, loadHandler: @escaping @Sendable (@escaping (URL?, Bool, (any Error)?) -> Void) -> Progress?)Discussion
If a destination app must access the represented file using a file coordinator, set the coordinated parameter in the load handler block to true.
To offer a representation backed by a file provider, return an NSURL object that points to your app’s file provider’s container. The file provider extension is then invoked to retrieve the file when requested.
To offer a representation backed by a file to open in place, set the fileOptions parameter to a value of openInPlace; in addition, return an NSURL object that points to your app’s file provider’s container. Open-in-place support requires that the file provider is visible in the Files app.
