A positive reading is “you must be coding Swift a lot lately, I acknowledge switching languages is hard and won’t fault you for it”.
A negative reading is “you are screwing this up enough for me to comment, you need to justify why”
If it’s intended to be reassuring then phrasing it so it’s clearly not a criticism is better. If it’s intended as a criticism then phrasing it clearly is also better.
The way I can see it being a joke, as claimed, is insultingly. Like a dentist watching a trainee dentist doing a filling and saying “you must have been doing masonry work lately”. Haha but the subtext is “you’re really doing a bad job of this”.
