As a Swift dev, the reason why it slows me down is that I often end up fighting the type system. I start with a concept, design my data structures on the whiteboard in a way that makes sense, then I try to code it and because of some detail in the type system it doesn't work, and I end up spending huge amounts of times wondering how to translate my concept into code. I don't have that issue in other languages. Also, the Swift compiler is really really slow.
