Isn't this right ? I tested it in XCode? What am I doing wrong?

What do I do here?

arrays.swift 
var todo:[String] = ["Learn Swift", "Build App", "Deploy App"]
printIn(todo)

Couple of issues here.

  • printIn is a typo, correct spelling is println.
  • your code didn't call the count method on the Array.
println(todo.count)

One thing I'd like to point out is that, sometimes when you tested your code in Xcode and it runs without syntax error; doesn't necessarily means it'll pass the code challenge, your code has to do exactly as the challenge described in order to pass it.

Hope this helps
