No code signing identities found

Hi there ,

I am new to ios development and i would like ask your help .
For over a week i am trying to test my app on my iphone device
but with no success .

I am using xcode 7.3 and got a warning saying "No code signing identities found with a Do it right button with some Git xtra
info i could not follow .
I tried doing some research online and i add my apple id but there signing identities are blank or a fade create button
and deleting ios certificates from keychain …but nothing .
Could any of you facing anything similar assist ?

Thank you for your time

I just upgrade to xcode 8 …not a problem to test my apps
straight on my device --thanx
