swiftenv: Swift version manager

Swift 3 development is so fast at the moment, that a new development snapshot is coming out every couple of weeks. To manage this, Kyle Fuller has rather helpfully written swiftenv which works on both OS X and Linux.

Once installed, usage is really simple. To install a new snapshot:

swiftenv install {version}

Where {version} is something like: DEVELOPMENT-SNAPSHOT-2016-05-09-a, though you can also use the full URL from the download page.

The really useful feature of swiftenv is that you can set the swift version on per-project basis. As change is so fast, projects are usually a version or so behind. e.g. at the time of writing, Kitura‘s current release (0.12.0) works with DEVELOPMENT-SNAPSHOT-2016-04-25-a.

We register a project specific swift version using:

swiftenv local {version}

i.e. for Kitura 0.12: swiftenv local DEVELOPMENT-SNAPSHOT-2016-04-25-a

Nice and easy!
