I updated to Sierra and my Xcode server has stopped working. I'm trying to set Xcode 8.2.1 (8C1002) as the build version and all I get is
This version of Xcode is not supported
I'm working on Swift 2.3 and can't yet update to Xcode 8.3.
At the moment it looks like my option is to downgrade to El Capitan.
Is there any other way to get Xcode 8.2.1 working on Sierra Server?
