It has just occurred to me that I did not set up my project properly in Xcode before submitting an update to my existing app in iTunes Connect.
In Xcode, under the build properties, I have set the Code Signing Identity to developer. I archived that build and then submitted it to iTunes Connect, but choosing the Distribution certificate from the dropdown during the submission process.
Does this mean that part of my app is signed with the developer certificate and the other with the distribution certificate? Or, is the whole thing signed with the distribution certificate.
Any help would be appreciated!
