Did you run the app connected to Xcode? Does the Xcode show any error? – kirander Oct 07 '15 at 07:56

I suspect that your default@2x.png
image is not a valid png
image. Please try replacing your existing default@2x.png
image with a new valid one and it should work.

Is it possible for you to share the gitHub link to your project so I could take a look. – Abhinav Oct 07 '15 at 10:47

Take a look at [this thread](http://stackoverflow.com/questions/19219291/black-screen-instead-of-launch-image-on-ipad-ios-7-0-x). It has a potential workaround to similar issue. See if this helps you. Also, take a look at the accepted answer. It seems to be a known reported bug to Apple. – Abhinav Oct 07 '15 at 11:04
