I think Swift is a viable competitor for C++ and Nim.<p>D won&#x27;t be fully a player in that space until the GC is fully optional - meaning no library code causes the GC to run unexpectedly.<p>I&#x27;m excited about Swift for desktop&#x2F;simulation&#x2F;gaming&#x2F;embedded development. I&#x27;m sure there&#x27;ll be a Windows port in the near term as well.
