Will Xcode 6.0.1 under 10.9.5 automatically sign my applications with the new „Version 2 Signatures“?

Question

I started my project with Xcode 5.1.1 under 10.9.4. I let Xcode generate all the necessary identities and profiles and do the code signing. Will Xcode 6.0.1 under 10.9.5 automatically sign my applications with the new, „Version 2 Signatures“?

Or do i have to manually change something for these new signatures come into effect? If so, what?

Answer 1

Yes, Version 2 signatures are automatically created when building under OS X 10.9.x or greater. (See Apple's Tech Note TN2206). The code signer is built into the OS and is independent of Xcode, which is why you can't get a version 2 signature from a prior version of OS X. (Note that 10.9.x or greater actually put a Version 1 and Version 2 signature in there because they are created differently and the Version 1 must exist for use under 10.8.x).

To verify you have the right signature, use the command codesign -dv <your app bundle>. Look for the Sealed Resources line which should have a version number on it.
