Swift is six years old.
The difference is that Apple, the most valuable corporation on Earth, has backed it 100%. They do occasionally kill initiatives (Can you say “OpenDoc”? I knew you could!), but not at the 50% rate that Google does, so I knew it wasn’t a big risk.
Also, I really enjoy the language.
It’s a long-term investment, and I don’t expect it to really start paying any dividends for at least another couple of years. I would be fine, sticking with ObjC, which I know will still be around for at least another decade.
But I’m at the point in life, where I want to work with tech that I enjoy.
