title: How to mute the capture sound in AVFoundation?
body: <p>I want to take the image using AVfoundation without any sound (yes, I have kept in mind, user choice will implement this feature)</p>
  
  <p>Two questions on stack overflow which gave the most information:</p>
  
  <ul>
  <li><p><a href="https://stackoverflow.com/questions/4401232/avfoundation-how-to-turn-off-the-shutter-sound-when-capturestillimageasynchrono">AVFoundation, how to turn off the shutter sound when captureStillImageAsynchronouslyFromConnection?</a> (no answer accepted and confirmed)</p></li>
  <li><p><a href="https://stackoverflow.com/questions/8621252/muting-avcapture-shutter-sound-on-iphone">Muting AVCapture shutter sound on iPhone</a> (<code>AVCaptureVideoDataOutput</code> is suggested)</p></li>
  </ul>
  
  <p>Both of the answer refers to capturing video frame, which I believe is correct. The problem is that AVfoundation library isn't really easy to master and I can't really get the hang of it (capturing image using <code>AVCaptureStillImageOutput</code> was itself tough for me).</p>
