...yes. You can. 6 is the minimum.

There didn't used to be this hard division between Xcode versions because of the compiler. If you were willing to do some reconfiguring, you could use newer GCC or "Apple LLVM" with the older Xcode.

Why are you not using the Swift 2.3 option in Xcode 8? It is going away in Xcode 8.3, but still, you can use more modern and stable dev tools.

I'm not sure why it hasn't been done yet; I've only been on the team for two months now. That would indeed be lovely. But the plan is to have one of our contractors move the entire project up to Swift 3. I don't know exactly when, though...

The OP mentioned Swift 2, not Swift 2.2 - even that upgrade can be non-trivial (2->2.2).

Eh, it is indeed 2.2, sorry for the imprecision. But yes, the concern is the time for the transition. Planned. We just have to fit it in.
