What irks you about iOS development?

[Chelmar]

I'm curious what kind of day-to-day problems game devs encounter while working with Xcode, Unity, or any other platform.

I also have a few specific questions:

1. App store review process. What kind of responses do you usually get back from Apple? How specific/helpful are they? (I've heard this has gone up from a 7 day to about 11-12 day wait now...)
2. Beta testing. How do you connect to testers, and what kind of testing feedback do you usually get back?
3. Performance. What do you use to profile your app, get crash reports, etc.? What do you like and not like about your tools?

Thanks!
