Is anyone having issues after updating to Yosemite 10.10?

I have updated my Mac to 10.10 Yosemite. Plus I have installed an update ‘command line tools’ on Mac App Store. My code remains same… When I run on ios and android (both emulators and real device), all I get is an empty tab bar and view. I am not sure if I am doing something wrong?
I have attached a screen shot… It looks exactly same in IOS emulator, genymotion, and Nexus 4 device.
App is working good on browser. No javascript errors whatsoever.



Can you start Safari, then go to Develop - iOS Simulator and open the index file. Refresh and then analyze the Developer tools console output.

I have fixed it with chrome remote debugger. There was an error with my javascript which didnt show up in web browser. Strange as it used to work before
