title: Delphi 10.2.3 E0776 exporting iOS app for Distribution
body: <p>Two days ago, I was able to create an export of this iOS app and successfully submit it to Apple's TestFlight with Delphi 10.2.3 and Xcode 9.2.</p>
  
  <p>Now, when deploying for the Application store, I get these error messages:</p>
  
  <blockquote>

  <p>Why would it mention "3rd Party Mac Developer Installer"? </p>
  
  <p>Unless Xcode is updating itself, nothing has changed other than improvements to the code of the project. Xcode is 9.2.</p>
  
  <p>The app deploys without issues to an iPad, in both Debug and Release modes.</p>
