I've had some incredibly fun (sarcasm) experiences with the review team for the MAS over the last few months. Reading that sentence got a belly laugh out of me.
The first major WTF that I had with the review team was their insistence that an app I had submitted was calling a private method. A method with the same name was present in an included library but rather than explain that to them I found it quicker just to remove the library (a workaround was simple enough). The hair pulling started when they again rejected the app for exactly the same reason. As the app relied on a heavy 3rd party framework it took a lot of investigation to understand what (wasn't) happening. Finally I took out a $50 tech ticket and after a week the engineer explained that the review team's tool for checking API usage was broken and it had nothing to do with my app.
The next time the review team rejected an app (seemingly within minutes of it going into review) because it was "producing garbage output". This time I just did a cursory review of the app before using another $50 tech support ticket. The app was sometimes writing files with the format somefile.ext.sb-randomstring. I suggested to the reviewer that the app was messing up an atomic write and given the sb- part of the filename had something to do with sandboxing. A week later the engineer explained what it was to me -- which was exactly what I had suggested.
My advice to anyone dealing with this is to spend zero time talking to the review team. Don't resubmit (unless it's something really obvious) and don't try to reason with them. Filing a $50 tech support ticket will basically guarantee that someone capable of passing the Turing test (have a conversation via iTunes Connect and you'll understand what I mean) will look into the problem. The tech support team will usually ask the review team to expedite your review once the problem has been solved -- something you'll rarely get if you ask yourself.
Did Apple at least refund your $50 when they discovered it was a bug in their own software?
the reviewer said it wasn’t sandboxed when it was
