title: Upload a new version of ios app to app store?
body: <p>I am new to iOS development. I have updated my application on new system and want to release the new version to App Store. I have gone through the steps to create a new build and upload the application for the first time on app store. However, I am not able to find a way to publish the new version of my application on the app store.</p>
  
  <p>My queries are as follows:
   1. What things I will need ready beforehand?(other than the updated source code)
   2. Do I need to generate/ reuse(If yes where can I get it?) any certificate or keystore(the one we use while signing the Android App)?</p>
  
  <p>I had gone through the following link :<a href="https://clearbridgemobile.com/how-to-submit-an-app-to-the-app-store/" rel="nofollow noreferrer">https://clearbridgemobile.com/how-to-submit-an-app-to-the-app-store/</a></p>
