I have one existing distribution certificate in apple developer portal. But, it is not working so I want to create another one in apple developer portal. But, there is an one option "Revoke" is available. If I select revoke the existing distribution certificate what will happen in XCode, KeyChain and the existing distribution certificate? and how can I create another new distribution certificate? Can you please clarify my doubt? The link is developer.apple.com.
