Xcode 'CodeSign error: code signing is required'

I've been working on an iPhone project with iOS 4.0. I just downloaded Xcode 3.2.4 with iOS SDK 4.1 so that I can work with the updated iOS. Upon opening the project in the udpated Xcode, I found that the target read 'Base SDK Missing'. I fixed that by following the instructions here.

Now when I try building targeting any version of iOS, I receive this error (with the corresponding version referenced in the error text):

CodeSign Error: code signing is required for product type 'Application' in SDK 'Device - iOS 4.1'

I have the Team Provisioning Profile created by Xcode installed, that Provisioning Profile has my certificate, and the Code Signing Entity selected is 'iPhone Developer: Aaron Milam'.

Any ideas as to what I could be missing here?

Most common cause, considering that all certificates are installed properly is not specifying the Code Signing Identity in the Active Target settings along with the Project settings. Change these from to iPhone Developer (Xcode will select the right profile depending on App ID match).

  • In Xcode , change from Simulator to Device (in the dropdown at the top of the Xcode window), so that your target for application deployment will be the Device.

  • The default ID which is a wild card ID is like a catch all iD, when associated in Code Signing (if you are using sample files to build, they will most obviously not have com.coolapps.appfile imports, in which case without the 'Team Provisioning profile', your build would fail. So you would want to set this in your

  • Xcode->Project ->Edit Project Settings->Build (tab)->Code Signing Identity (header) ->Any iOS (change from Any iOS Simulator)->(select 'iPhone Developer' as value and it will default to the wildcard development provisioning profile (Team Provisioning Profile: * )

and also (VERY IMPORTANT)

In my case, locking and unlocking login-keychain from Keychain Access did the trick enter image description here
