Can't donwload app on to Iphone/Ipad


Hello, I wrote the first application with no problem, but couldn’t download it on to my Ipad/Iphone, which are fully updated, and it’s giving me this 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 am running Xcode 4.6


Are you a registered developer with Apple and have you paid the $99 for a year subscription ?

If so - then make sure you have installed the development profile on your machine.
