Is there a way to compile a release iOS app without upload to Apple's system

What would the settings on voltbuilder.json be to compile a release iOS app without upload to Apple’s system?

Yes. If you don’t supply an itunesAccount in voltbuilder.json, you can download the .ipa after the build.

Simply remove:
“itunesAccount”: “xxxxxx”,
“itunesAppPassword”: “xxxxxxx”

from voltbuilder.json

Thanks guys
