Context: Xcode 26.3, iOS 18.7.6 on iPhone Xs
In this iOS app, I call UIActivityViewController to let user Airdrop files from the app.
When trying to send a URL whose file name contains some characters like accentuated (-, é, '), the transfer fails.
Removing those characters makes it work without problem.
The same app running on Mac (in iPad mode) works with both cases.
I also noticed that even when airdrop fails, there is no error reported by
activityVC.completionWithItemsHandler = { activity, success, items, error in }
Are those known issues ?
