Except sometimes Apple rejects your app such that you can't do anything to fix it. They straight up tell you that your whole concept isn't allowed to exist on the app store. I think I've seen a couple of stories about this a while ago. Or if there's any semblance of UGC, you're supposed to have a moderation team that would enforce Apple's ridiculous policies. Oh you're an individual and don't intend to turn that into a company? Tough luck, sorry.

They do? I was under the impression that they don't.

I specifically remember submitting an app, and getting denied. The response we got was relatively vague, saying it was breaking ToS. No screenshots, no call or anything of the sort.

This was the first submission though.
