title: What happens if an api your app uses is deprecated after your app is released?
body: <p>If you release an app that uses an api that is later deprecated (after the release of your app), then what happens ? </p>
  
  <p>What if you never update your app after it is released on the store ? Will it work with all future versions of iOS ? </p>
  
  <p>Will the app still work when the api goes away in later OS versions? Or will the App Store just prevent your app from being downloaded to future OS versions ?</p>
