How do I check that my app is iOS7 compatible according to Apple Standards?

Question

According to Apple:

Starting February 1, new apps and app updates submitted to the App Store must be built with the latest version of Xcode 5 and must be optimized for iOS 7.

How do I check that my iOS app conforms to these requirements ? Is there a checklist somewhere ? If I do not get any warnings when uploading to AppStore today, can I assume there won't be any problems by February ?

I believe my app is 'optimized for iOS7', but Apple only refers to their Human Interface Guidelines, where I think some of the requirements are subjective.

I should mention that I think I have all the basics covered - using SDK7 and XCode 5, got all the new icon sizes, etc.

Answer 1

The iOS 7 transition guide is a good place to start. After that, all your app submissions must be compiled against the iOS 7 SDK, using Xcode 5.
