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)
CodeSign error: code signing is required for product type 'Application' in SDK 'iOS5.1'
What does this mean ? and how to solve it ?

Code signing your app assures users that it's from a known source and hasn't been modified since it was last signed. Before your app can integrate app services, be installed on a device, or be submitted to the App Store, it must be signed with a certificate issued by Apple.
To help ensure that all apps come from a known and approved source and haven't been tampered with, iOS and iPadOS require that all executable code be signed using an Apple-issued certificate. Apps provided with the device, like Mail and Safari, are signed by Apple.
It means you haven't assigned a provisioning profile to the configuration.
Usually it's because "Any iOS SDK" must have a profile and cannot be set to "Don't sign".
All this and more is answered in the TN2250 Tech Note about Code Signing and Troubleshooting.

One possible solution which works for me:
Bravo!

This error was caused, for me, by different circumstances. A downloaded project tutorial had a default setting of [Project]>Targets>Build Settings>Architectures>Build Active Architecture Only>Release = "Yes." I wasn't intending to build a release, so the solution was to set Release (which presumably requires not just a developer profile but distribution profile) to "No."

You can get around this by using the simulator if you don't actually need to be deploying to a device. That solved it for me.
