I am developing my first ever iOS mobile app. I am using OS X Lion 10.7.5 with Xcode 4.6 for development. I completed my app and now want to test on a device. When I am trying to connect iPad Air with iOS 7.1 for testing, Xcode is giving an error:
Xcode cannot run using the selected device. No provisioned iOS devices are available with a compatible iOS version. Connect an iOS device with a recent enough version of iOS to run your application or choose an iOS simulator as the destination.
I googled and came to decision that I need to use Xcode 5 if I want to test device with iOS 6.1 and above but I cannot install Xcode 5 as it requires OS X 10.8.4 and above. I decided to upgrade my OS from Lion to Mavericks.
Just wanted to know if I do so will it create any problems in my already developed app? I don't have time to take a backup with Time Machine.
