I just updated my Xcode to Version 7.0 (7A220) and out of the blue I got this message when I connect my iPhone to xCODE to test an application :
iPhone from nuñito (unavailable)
and everything is fine from iTunes !
I've tried all these solutions !
Ineligible Devices section appeared in Xcode 6.x.x
iOS version in my phone running -> iOS 9.1
iOS version in my app's deployment target –> 9.0
