send a file TO iPhone via AirDrop

In Swift I have figured out how to send a file FROM the iPhone to my Desktop using AirDrop… but can’t seem to figure out how to associate my app in such a way that the documents folder of my app on the iPhone is a destination to recieve them

The file does arrive on the iPhone, I just have no idea how to associate it with a particular app

I’m asking this here because I feel the answer might also benefit Xojo users…

well SO far it seems you just need to add this to the pList file … but I now need to determine that it actually ended up where I wanted it… Seems the app itself doesn’t control AirDrop… so it isn’t a single step operation
