The fact that macOS doesn't have a built in history for the clipboard is the problem there imo. I use pasteBot and I think macOS is broken without it (which of course means iOS is broken and cannot be fixed by a third party).
I use JumpCut. I still don't want my stuff on one machine erased via the other unless i specifically connect them via vnc.

The blog post about it seems to imply you have to do an extra swipe down to put it in the clipboard manager for every copy...
