Xcode Organizer: Valid Signature ID Not Found

Question

I already have one application published on the App Store, but I developed it using Adobe AIR on a Windows PC.

Now I would like to learn my own programming with iOS 7, I bought an O'Reilly book, MBA with OSX 10.8.5, Xcode 5.0 and iPhone 5c.

I assume that in order to try the sample applications on my device, I need to create a lookup application id and development profile and install it on my iPhone.

I think this worked well - I see the profile at the bottom of the settings → General → Profiles:

But the Xcode organizer shows a warning triangle and a warning. A valid signature ID was not found :

What am I doing wrong? I searched for SO and confirmed that my certificates use system defaults ...

UPDATE: yes, I added a certificate to access Keychain:

Answer 1

First, delete the certificate without the private key from the key fob - it is useless and may generate errors in the future.
Open your access to the key chain and complete the certificate signing request (in the top menu, select "Access to the key chain" → "Certificate Assistant" → request a certificate from the signing authority). You should see this window

Select saved to disk and enter your email address. CA email address not specified.
Specify the location of the generated SigningRequest certificate file where you want. Then go to the Apple Developer Center and create a development certificate. Follow the normal procedure, select the iOS application, specify the created csr file, generate, download, add to the keychain. Revenue =)

Answer 2

I exported the .p12 file certificate from the old / original mac via the KeyChain application, and then imported it again into the new Mac using the KeyChain application, then on the apple dev website I edited the provisioning profile, saved it, uploaded and re-registered it in xcode
