Apple Checks App Store Submissions Using Software?

If you’re wondering how Apple managed to process so many of the applications that submitted to it for approval in the App Store, the answer seems to be that Apple has just recently started running the apps through a static analysis tool to look for private API calls. Private APIs are used to access features that Apple does not want to make available to third-party developers. With this latest system, it’ll be much easier for Apple to find use of private API calls, which will be much harder for a human tester to find.
