@kaustubh-kabra thanks for the PR! Can you confirm for me that you are able to run xcrestore after xcunsign and that it restores Xcode correctly on Sierra with this change?

If you have fastlane installed, the best test would be to run fastlane run verify_xcode 8.0 after unsigning and then restoring. If the verify passes successfully, we can be confident that the restore worked as intended.

I don't use Fastlane but I confirm restore is working fine after unsign -

Awesome, thanks for the confirmation!
