Swift for embedded starter kit

Hi! :waving_hand: it’s been more than 10y since I played with embedded. Since it is possible now to do this in swift. I was wondering if there is a good starter kit/hardware pack people recommend?

I looked at template project like raspberry pi and bearbone ones. And was interest what are you all opt in to?

If I want to start building a plane :airplane: and see how far I go. What would be best hardware for myself?

Please recommend. Thanks :folded_hands:
