I’m a Swift newbie, going through the Swift books (2.1 and 2.2). I’m a bit
confused and I’d appreciate your help with setting up a good environment.
1. I have Xcode 7.2.1 installed. This seems to correspond to Swift 2.1.1
which I assume is the stable version.
2. There are release snapshots for 2.2 available on swift.org.
Q2.1: can one run in parallel Swift 2.1.1 and 2.2 snapshots? If yes, what
setup do I need?
Q2.2: I read that 2.2 snapshots do not include the Package manager. Can it
be installed separately?
3. I’ve heard about the upcoming big 3.0 Swift version.
Q3.1: are there development snapshots available?
Q3.2: as above, can one run 2.1, 2.2, and 3.0 snapshots in parallel on the
same system? (if yes, please do include any links on how the setup looks
thanks a lot for your help,
