Hi:
I have a Swift Package, which contains C++, ObjectiveC++ and Swift code. It can be compiled under the previous version of XCode 11.0, MacOS 10.14.6, but it can't be compiled after updating to MacOS 10.15, XCode 11.1. I hope someone can help me to find a solution, thanks!
Hey. I am not exactly sure what caused this regression but please file a JIRA at bugs.swift.org. It seems like the block.h file from your cpplib is conflicting with Block.h in the SDK. I was able to compile your package after renaming it to something else.
