I am using xCode 4.3.1. After i created a project, i build it and tried to Archive. Then i got an error saying; (This is my first project in xCode 4.3.1)
The other issue here lies under Code Signing Identity under the Build Settings. Be sure that it contains the Code Signing Identity: "iOS Developer" as opposed to "Don't Code Sign." This will allow you to deploy it to your iOS device. Especially, if you have downloaded a GitHub example or something to this effect.
