Ionic package build ios BAG

ionic package build ios --profile NAME --release
after downloading package, my app show only “APACHE CORDOVA device is ready” screen

I find information, that it can be because it lost WWW folder.

But, when i emulate ios, it run normaly
Any ideas?

I had this same problem today. I use the online service to the build of iOS version, and found the same screen on my app.
Decided as follows, on the command line, forced to use the cordova-ios lib version 3.9.2:

$ ionic platform add ios@3.9.2 --save

After that I made a new build and the app work again.
But I think that this problem has to be solved by ionic team so we can make the build using the latest version of cordova-ios lib.
