I’m lucky. I’ve just started a Mac app, and I plan to write
it in Swift.
I’ve heard other developers say they want to wait about a year,
and I totally understand that attitude. It’s reasonable to assume
that Swift code written today may not compile in a few months —
it’s a work in progress.
But my thinking is this: if I start using it now, I can provide
feedback, and that feedback will help shape the programming
language that I’m likely to use for the rest of my career. Maybe
I’ll have a ton of feedback, and maybe I’ll have none — but I’d
sure hate to have missed my chance to help.
We came into WWDC thinking we might have to approach Vesper for Mac with a new UI design sensibility. We came out thinking we should write it with a new programming language.
