It sounds like you&#x27;re assuming the majority of (iOS) App Store rejections deal with using unofficial&#x2F;restricted APIs. My guess is that&#x27;s relatively rare.<p>Most of the apps caught in the review process are probably those that fail other guidelines (usefulness, privacy concerns, illegal&#x2F;inappropriate content, poor UX&#x2F;quality, excessive crashing, etc). Most of those things can&#x27;t be caught by automated means, and the content-related things can certainly be changed after initial review.<p>I&#x27;ve personally worked on several apps that significantly modify app behavior after being published - not so much to bypass any review requirements, but rather to adapt to changing business needs without waiting to publish a new release.
