How can I remove a previously installed development provisioning profile from xcode?
I have yet to find a way to delete provisioning profiles individually (Xcode 5).
The only way I can get them to go away is by removing the App IDs related to the provisioning profile(s). (In Certificates, Identifiers & Profiles in the Member Center)
Obviously this might not be optimal for you - but if you have been using a test app id it is the way to go.
