I'm currently running iOS 7.1 beta 5 on my iPhone 5S, and I also am running Xcode51-Beta5. I'm new to app development in general, but definitely know my way around Xcode and code in general as I come from a PHP background.
There is a Hello World application that is compiled with Cordova, which you can open in Xcode to emulate on an iOS device or deploy to your device for testing.
Without tweaking anything, the Hello World app runs fine on all simulators for iOS devices, however, when I attempt to deploy it to my iPhone 5S, I get 10 build errors and it fails. I tried turning off Code Signing for the project which was suggested in another Stackoverflow question, however, that also didn't work.
The errors I get: http://prntscr.com/2tqqj3 and in more detail: http://prntscr.com/2tqqse
Any help would be greatly appreciated!
