How many other two year old languages are there in large scale use? It's not surprising there are issues in compiling things. I've used so many languages early on since I started in the 80's and you can always find some syntax the compiler doesn't like. Given the pedigree of the people building Swift who also built the entire llvm system it's pretty good for something still in diapers. Now take XCode, that is some real drunk.
