I like it, being able to start with a shell script and then evolve the tool to a static binary is pretty neat, I do that all the time with ActionScript I don't think it's trying to be a "jack of all trades", sure Bash can do plenty but when you reach few hundred lines of Bash and start to fight against the syntax to do simple things well... The shebang line is there to be used, you can use sh, bash, etc. but there are other citizen like perl, php, python, etc. so why not swift or anything else if it help you build quickly command-line tools?
