My feeling is that sort of thing is going to be the experience when using Swift for anything but the smallest of scripting tasks for the next little while. The libraries just aren't available in a format where using them's easy enough to bother with.
swift scriptname.swift into the terminal is a whole lot better than
xcrun whatever it was we used to have to type though, so small steps. And as Stencil and projects like it show, people are filling in the missing pieces. So one day soon, fingers crossed.
This post marks the start of an experiment in more short form and also more regular writing. Pump up the volume!
