I've been learning Swift lately, and I have to say I've *really* come to enjoy it. Sure, it has it's problems, but I feel like you always can find a solution to them, and I just really appreciate the sheer pragmatism.
Also: result builders are my favorite way to define UIs that I've ever used. It *actually* feels like a programming language that takes UI programming seriously and is willing to prioritize making UI programming ergonomic!
