To others not using RubyMotion and don't think that deleting the app is acceptable (as in, you want to do upgrade testing). Check out the bottom of these docs from Apple:

https://developer.apple.com/library/ios/technotes/tn2319/_index.html

It looks like they changed something in 8.1.3 to check for this new rule.

The Fix

"[Add] the installed application’s application-identifier value, as logged in the second parentheses, to the previous-application-identifiers entitlement’s array value for the app being installed (by resigning it or re-building it) and requesting new special provisioning profiles as shown below."

previous-application-identifiers

    {Your Old App ID Prefix}.YourApp.Bundle.ID

EDIT:

In order to do this, you need special provisioning profiles. You can request these from Apple: "To enable signing with the previous-application-identifiers entitlement new special provisioning profiles are required that can be obtained by going to the Contact US page and requesting them." (from the docs linked above).
