Swift 3.0 Migration

[alexpovh]

dshb didn't install for me via brew on 10.12, looks like it can't build swift 2 anymore

SMCKit: beltex/SMCKit#27
SystemKit: beltex/SystemKit#25
CommandLine: jatoben/CommandLine#83

build appears to be failing with HEAD https://gist.github.com/ilovezfs/501cb85c702a9e001e122293890ba65c

It has dependency on this beltex/SystemKit#25. After it's merged, libs directory submodules need to be updated to point to swift 3 versions and then it should work!

Anyone wants to clone&run - I've updated this branch to use Swift 3 forks of SCMKit, SystemKit and latest version of CommandLineKit: https://github.com/ealeksandrov/dshb.

git clone --recursive https://github.com/ealeksandrov/dshb
cd dshb
make install

Thanks @alexpovh and @perfaram for your PRs.

@ealeksandrov yes that compiles on 10.11 with Xcode 8.2.1 and on 10.12 with Xcode 8.3.3.

@beltex what needs to be done to get @ealeksandrov's changes merged?

@beltex Gentle ping on this. We're bottling for macOS 10.13 High Sierra in Homebrew now and still don't have a Sierra bottle. Also, we've lost the ability to rebuild dshb at all since Homebrew has dropped Yosemite support, and our El Capitan CI uses Xcode 8.2.1.

@alexpovh have you looked at refreshing this for Xcode 9 and for jatoben/CommandLine#78 ?

[beltex]

Thanks so much for this @alexpovh! And so sorry about the super late response on this folks!
