I was trying to make use of the ipa file that Xcode creates at the end of the integration process, but for some reason it seems like it doesn't want to create this file until every single step in the integration has run, including the post-integration triggers. This makes absolutely no sense to me, and makes me think maybe I'm doing something wrong. Did you also have this problem? Is this why you have to create the ipa file yourself?
