I started using swift with a lot of enthusiasm for the type system, but at times it was a huge time suck. There were lots of obscure interface types that read like BipartisanPoliticallyCorrectSequence<T> that made writing my own generic utilities challenging. Documentation for that stuff was very poor and the source code was often totally inscrutable due to the implementation of core types in c++ and the overall complexity of the compiler.

I recently saw Chris Lattner talk about Mojo and he made passing reference to Swift trying to do too much with the type system. It’s telling that a guy with his experience is trying something more like zig’s comptime approach to types after two decades of generics.
