Swift has a lot of power to become a really good scripting language so I started translating some scripts that I had to Swift. Soon I found that I could write some little helper functions to make things easier while surfing my computer.
Foundation is a really good API, and this give us a loot of power to make cool things in our Scripts. We have all the power that our Applicatoins have, and this is huge. I writed a helper class and it's now in GitHub, CommandLineHelper. It just conatins some functions to deal with directories and files hiding the Foundation API.
One of the things that I still miss is a really good HTML scraping library like other languages have. I hope that soon we start seeing libraries that not only help us develop cool applications but also write great scripts.
I would love to se Swift not only as a big scripting language but also as a big server side langauge.
