So they're confirming it's a bug? That's a bit reassuring!

So, what did they share?

crap

Whaat?!

Awesome! Which simulators? What does that mean? I've been testing mine on Swift Playgrounds for Mac, can it be run on Mac instead of iPad? Or is there a way to test it in an iPad simulator?

Exactly the same situation for me, except I'm with a Brother MFC-9330CDW (even though it sounds like a password, I've remembered it at this point...) Scanning crashes in the Preferences but is the only option available in the Brother App, no printing.

What the hell are they doing... Drivers should be something they should worry about...
