I am trying to port my sandboxed macOS app completely over to iOS using a Catalyst target and SwiftUI.
There appears to be an issue when trying to drag to the Finder in Catalyst (and in SwiftUI in General). For some reason, the Finder will not accept multiple file drops, only a single file.
On my macOS (non-Catalyst AppKit target), I overcame this by dropping multiple files to a UTType of .folder, and the OS accepted the folder. This workaround is not available for iOS because .folder is a macOS-only option.
I have a test app to illustrate the issue. Hopefully someone can help.
