@tolmekian1453 not an answer for your question, but I am still struggling to get working, I have followed all the steps in the installing guide, the share extension is there in the share menu, but when I click on it nothing happens at all. Could you please tell me if there is any further steps that you have done to get it working?
I got it to work by editing the code to return values from every provider, not just the first one that has data. It's hacky because I don't recall how to join the async blocks in ObjC at the end, so I just used an 0.4 second timer, lol.

Maybe someone more ObjC-experienced can make a PR.
I got everything working so I can share links from Safari, but when I share from the Apple News app,
await ShareExtension.data()
only returns{"type": "text/plain", "value": (the title of the news article)}
. I'm using the same info.plist I used in a native app I wrote before that had a share extension that worked with News and Safari alike.The native code I used in that other app:
