How many other two year old languages are there in large scale use? It&#x27;s not surprising there are issues in compiling things. I&#x27;ve used so many languages early on since I started in the 80&#x27;s and you can always find some syntax the compiler doesn&#x27;t like. Given the pedigree of the people building Swift who also built the entire llvm system it&#x27;s pretty good for something still in diapers.<p>Now take XCode, that is some real drunk.
