Super excited! I will totally be exploring Swift for quantitative work. Julia has been great so far, but a lack of good IDE tooling is making a large codebase difficult to navigate and keep clean. Python has even less type safety than Julia. Swift has a REPL! Go doesn&#x27;t, and its lack of generics makes writing most algorithms very limited (there isn&#x27;t even a matrix 32 library, just 64 bit). Java has horrible native interfacing. C# is pretty anemic on Linux. C++ has too many gotchas, slow compile, to feel productive. Bonus: Swift libs will probably be very easy to deploy on both Android and ios.
