I think just the fact that you were able to build a game with just 4 hours of learning a new language speaks volumes about Swift's barrier to entry. Well done!

I think it speaks more to the author's prowess, not to the fantastic magic powers of Apple's latest walled garden.

But the code was just a port/convert, seems relatively non-trivial to do that in 4 hours.

I supposed "relatively" is the key word here. To me, that'd be a great feat. To others, not that special.
