Cordova IOS white screen at first start

I’m trying to run my app on XCode for building an ios app. On the browser it works perfectly, however, on IOS it doesn’t. The XCode simulator starts the app as everything is fine, but there’s nothing but an empty white screen. No particular error logs either.

See the mobile-config.js file, and the entire source code, here: https://github.com/eminx/pomegra-next/blob/master/mobile-config.js

Help appreciated!
