Xcode 7 Error "no code signing identities found" When Build Using Free Provisioning Profile

Question

Recently i'm trying to sideload xcode 7 app to my iphone. But I always got this error: https://drive.google.com/file/d/0B0B4cWQXc78eSUFLakJkZ1N1THc/view

When i click that 'Fix issue' button I got popup like this: https://drive.google.com/file/d/0B0B4cWQXc78eaHhnendJVUVkWVU/view

This is a new fresh project and never signed on another mac, so I dont have that "developer certificate" and i'm using Free Provisioning Profile. I click that reset button but that popup always come again. I hope someone can help me to solve this problem -_- Sorry for my English and my reputation is 1 so I can't post an image.

Regards, Alex

Answer 1

After Stackoverflowing... for hours, clean rebuild derived data ecc... I found the solution "Moving to trash" the provisioning profile I already have and downloading again, but first I repeat DELETE IT!

Answer 2

import your developer certificate and add it into keychain check Exporting and Importing Certificates and Profiles help and apples troubleshooting page

apple documentaion says

If the certificate already exists in Member Center, a “Your account already has a valid certificate” dialog appears. Typically, this happens when you move from one Mac to another. If possible, export your certificates as a developer profile file on the other Mac, and then import them on your new Mac, as described in Exporting and Importing Certificates and Profiles. If you don’t have a backup of your developer profile, click the “Revoke and Request” button when the “Your account already has a valid certificate” dialog appears.
