From https://adactio.com/journal/15972 “When the share() method is triggered, iOS provides multiple ways of sharing: Messages, Airdrop, email, and so on. But the simplest option is the one labelled ‘copy’, which copies to the clipboard. Here’s the thing: if you’ve provided a text parameter to the share() method then that’s what’s going to get copied to the clipboard—not the URL.”
