Hi All, Just bought a new Mac and downloaded the latest Xcode. Version 12.0.1 from the App Store. I am updating my distribution certificates and coming from HighSeirra and Xcode 10. I'm getting the error Photos requires C11 or later and requires the GNU11 [-std=gnu11] fix. Thats not available in Xcode 12 only a timidly written 'gnu11' that doesn't work. Adding GNU11 [-std=gnu++11] manually via other doesn't work either. Anybody got another fix? Thanks, Paz
