You may have heard about changes in the Swift community <https://lists.swift.org/pipermail/swift-evolution/Week-of-Mon-20170109/030063.html>, and we wanted to make it clear that Apple is strongly committed to open source and the LLVM and Clang tools.
Our compiler toolchain has been, is, and will continue to be based on LLVM and Clang. We remain one of the largest users of and contributors to LLVM, as evidenced by our extensive contributions to the project and the breadth of Apple employee participation in the overall project and the LLVM DevMtg in November. We’re as committed as ever.
Sr. Manager, Low Level Tools
