> Swift actively distracts me in that endeavor by making me answer questions I really don't want to answer right now. Yes, stuff might be less correct in the meantime, but heck that is what I want during the design phase. Find my concept, sweet spot, iterate, pivot quickly.

This is also what annoys me about TDD - writing code is a process of refinement - if I know exactly what the API I am going to program against looks like, if I know the API I will offer and I know the internals of my code are before I write code then hell, I have done it before.

Often times coding is exploring.
