title: Non-public selectors
body: <p>Got the following warning when trying to validate my binary. <strong>"The app references non-public selectors in Payload/app.app/app: cache, decoder, hasPhotoType"</strong>
  Problem is I don't know how to get to "Payload/app.app".
  Pretty sure I am not using "hasPhotoType" anywhere in my codes, ie, I cannot locate "hasPhotoType" using Xcode search functionality.</p>
  
  <p>Strangely, I am not getting the warning error when I am in normal window. Only when I tried to "validate" the binary, then I get the above warning</p>
