title: How can I detect if the currently running app was installed from the app store?
body: <p>Is there a way in iOS to programmatically check if the currently running app was installed from the iOS App Store? This is in contrast to an app that was run via Xcode, TestFlight, or any non-official distribution source.</p>
  
  <p>This is in the context of an SDK that doesn't have access to the app's source code.</p>
  
  <p>To be clear - I am looking for some signature, so to speak, given to the app (presumably by Apple), that will, without dependence on any preprocessor flags or other build configurations, be accessible to any application at run time.</p>
