This question already has an answer here:
I updated my iPad 2 OS to version 7.0.2 and updated XCode 4.6 to XCode 5. Device is detected in iTunes, but not in XCode 5 and I get an age old message No provisioned iOS devices are available with a compatible iOS version.
I see a valid provisioning profile in Windows->organizer. I closed the XCode and started again but device not detected.
What might be the issue?
check in your Xcode Development Target
match your iOS version with Development Target
its work for me
