If anyone here are experiencing the same problem like adagar & laoniustudio try installing your app using TestFlight. Instead of installing the .IPA file right away to your iOS Device through iTunes.
You can download TestFlight on the AppStore, and download your app through testflight, but in order to do this, you need to have "Application Loader" in a Mac OS.
Open up "Application Loader" upload your compiled .IPA file. This process will upload your .IPA file to your iTunes Connect.
Once it's uploaded in iTunes Connect go to "My Apps" click your Apps, click "Releases" then add your email to the "Internal Testers" list and enable the "TestFlight" options in your desired build.
Once its enabled, go to your email address (with your iOS Device) and click the link provided by itunes connect in your email inbox, it should be downloading your app.
The method above is the RECOMMENDED method by Apple instead of installing it manually from iTunes.
If this still doesn't work then there must be something wrong with your build settings in IntelXDK or C2 Project Settings.
