Swift Sequences

Thanks for the post @gfontenot. I’m still reading over it to grock it. I was wondering if there was any advantage to this over using Process.arguments to get the arguments instead.

Do you mean NSProcessInfo? I’m using C_ARGV as a bit of an artificial restriction on myself because I want to see how far I can get without importing Foundation.

No, just Process.arguments. Looks like you can also do NSProcessInfo.processInfo().arguments but that does need Foundation. Process doesn’t. Here’s the entire contents of my main.swift file for playing around:

println(Process.arguments)
println(Process.arguments.count)

Obviously this doesn’t make for a good blog post or help anyone understand Sequences.

Oh, wow. Didn’t know about Process. That’s neat. There is far too little documentation right now. Thanks!

In fact, Process doesn’t even show up in the generated header. How did you find out about that?

Ha. So apparently he’s the only one that knows about that Struct. He pinged us on Twitter about it too.
