I had this same problem today. I use the online service Ionic.io 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.
