Implement drag-and-drop in SwiftUI by conforming your data model to the Transferable protocol and using the onMove modifier to enable smooth list reordering on macOS 13 and later.

The Transferable protocol works by defining the data representations your model exposes, allowing SwiftUI drag sources and drop destinations to share items seamlessly across list views and other macOS applications.

Yes, you can accept file drops from Finder by applying the dropDestination or onDrop modifiers to your SwiftUI views, specifying the Transferable representations your app expects to receive.

The best way to support cross-app drag-and-drop is conforming your data to Transferable with appropriate representations, then using onDrop and dropDestination modifiers to handle incoming items from external macOS applications.

Yes, you need macOS 13 or later to use the Transferable protocol and its associated drag-and-drop modifiers like dropDestination, as these APIs are built for modern SwiftUI compatibility.

onDrop fails to accept external file drops when your Transferable conformance lacks the correct representation types, or when your dropDestination modifier is not properly configured for the incoming data format.
