Under Xcode 4 I was able to export an unsigned IPA in order to send that to clients with Enterprise accounts for resigning. With the upgrade to Xcode 5 this option has been removed. I found a similar question that found a work around for Cocoa apps, but this won't work for iOS apps as it yields a .app file.
Does anyone know how an unsigned IPA can be generated from Xcode 5, or know of another way to give something to my client for resigning that doesn't involve trading certificates or the project itself?
