body: <p>My iOS app has gone through multiple releases. I just added another feature (playing audio files using facebook audio360 tbe format), and the app got rejected with the wording:</p>

  <p>I am not performing "code obfuscation and selector mangling", has submitted an appeal, which was also rejected pointing to the same guideline.</p>
  
  <p>I am using objective-c with some swift, Xcode 9, Product -> Archive -> Submit to App Store... Is it doing some obfuscation that I could turn off?</p>
