No iOS Development certificates found

The trick that did it for me was to log into developer.apple.com and manually create a dev certificate and then manually create a provisioning profile. I have only one team with only one member (me) so there was no way for me to approve a certificate. When I tried to do it automatically through the Xcode organizer, the error just persisted.

Same error message here. Seems to have multiple sources.Mine was that I have a developer account and joining two teams.In one team i had no Certificates at all. In the past this did not cause any problems. In Xcode Organizer I could choose which team I try to fetch the Provisioning Profiles. And if chose the team for which I had Development Certificate the Provisioning Profiles got downloaded with no error.I think, with the new improved Member Center starting from april 2013 the Organizer fetches automatically all team accounts - without asking for a specific team. As one team had no certificate at all, the process of fetching for all teams stop with this error message.

Solution (for this problem) is to add a Development Certificate for ALL teams.

Having just gone through this myself, I highly recommend you contact Apple Developer Program Support and have them walk you through the process of resetting your certificates and profiles. It is not a difficult thing to do manually, but there are lots of ways to muck it up (I speak from experience) AND the more people that call the more likely they are to continue improving the process.

That said, the short(-ish) answer is to delete all of your developer and installer certificates from Keychain, then delete all certificates and provisioning profiles from the portal, then create them all again from scratch, and then refresh Xcode to bring them all in.

Oh, and be sure to back it all up when you're done!
