[swift-dev] Swift 2.3 branch build broken

[Matt Rajca]

Hello,

I’ve been unable to build Swift 2.3 with both Xcode 8 GM on 10.12 and Xcode 7.3/8 GM on 10.11.

Trying to build with Xcode 8 GM on 10.12 and 7.3 GM on 10.11 results in: "error: protocol '__BridgedNSError' requires '_NSErrorDomain' to be available on OS X 10.9.0 and newer” errors.
Building with Xcode 8 on 10.11 results in errors in the CoreData overlay (namely NSFetchRequestResult protocol declarations being missing).

What’s the supported configuration for building the Swift 2.3 branch and will there be an updated 2.3 GM release tagged?
