When I submit build to AppStore I see errors:
ERROR ITMS-4088: \"No software found with apple_id: *\" at SofwareAssets
ERROR ITMS-4238: \"Redundant
Issue is appearing because you have already submitted one binary to iTunes connect(You can check that under the build option in iTunes connect).
I think you need to add version 3.1 in the iTunes and in your code, then try to resubmit app.
Here are the more info:
Go to My Apps - > Click on your apps that you need to submit -> Scroll down and you there you will see Build option.
Please see below screenshot:
