> A lot of people in the western world don’t realize how much taxes limit their options. You can end up paying almost half your income in taxes, which basically means you’re working for the government for 180 days a year. I think I can find better ways to use the money I make for the benefit of society.
ok, so he's basically suggesting to get of rid government. I respect different stands on the size/role of the government in society, but this is just a weak argument. What works out for him, won't work out for everybody.
Definitely Swift. But:
1) If you plan to develop a SDK/lib compatible with both Obj-C and Swift and don't want to adapt to new Swift changes coming forward
or
2) You absolutely can't stand SourceKit related bugs in XCode happening now and then.
then consider Obj-C.
Would go pretty far to use Swift over Obj-C anyway, so I can deal with both 1) and 2) and still use Swift. It will just get better, so probably best to go Swift sooner than later.
