title: Update IOS app, does it need to be signed with the same xcode account
body: <p>I have hired an apple developer where he coded my app. To publish the app, I provided him with provisioning profile and certificate. He also has the ITunes connect credential.</p>
  
  <p>However when he pushed up the build, he signed it with his xcode ID.</p>
  
  <p>Basically my question is, if  I want to push an update in the future , does it have to use his xcode ID?  OR can I submit an update from any other xcode as long as I have the profile, certificate and ITunes connect credential </p>
  
  <p>Thank you</p>
  
  <p>PS: Coming from Android background so it is very confusing</p>
