IPA File not being created

I have a simple app generated using the cli, and every time I run ‘ionic build ios --device --platform --buildConfig ./build.json’ no IPA file is created for the application. If I take the same project and execute ‘cordova build ios --device --platform --buildConfig ./build.json’ the IPA file is created. I’m going to assume this is a bug with the latest Ionic2 / Ionic App Script. Here is my environment info:

Cordova CLI: 6.4.0
Ionic Framework Version: 2.0.0-rc.3
Ionic CLI Version: 2.1.12
Ionic App Lib Version: 2.1.7
Ionic App Scripts Version: 0.0.46
ios-deploy version: 1.9.0
ios-sim version: 5.0.11
OS: OS X El Capitan
Node Version: v6.9.1
Xcode version: Xcode 8.1 Build version 8B62
cordova-ios: 4.3.0

It seems the main difference is when running ‘cordova’ the final output line tells me that xcodebuild runs and ** EXPORT SUCCEEDED **. I do not get this when running with just ‘ionic’. I didn’t see an open issue on Github for this so I figured I would ask here before I create a new issue for this.
