iOS Swift Basics (retired) Collections What is an Array?

I believe I am answering this question correctly with the println("The number of items in my todo list is \(todo.count)"

The question asks print out the number of items on the todo list using println, I answer essentially with println("number of do list items is (todo.count)") and I keep getting Bummer Try Again. It would seem you're looking for use of .count, but what is missing from this?

arrays.swift 
var todo : [String] = ["Learn Swift","Build App","Deploy App"]
println("The number of items is \(todo.count)")

That's the compiler being picky - you just need println(todo.count)

At times, the tests behind the code challenges are narrowly interpreted!

Thanks Steve, I just found the other answer, I should have searched the forum first. Again thanks for the answer, I was trying to be all smart and use interpolation and format my answer. :)

There are many examples where the simplest answer is what it is looking for - added flair and style isn't the way forward when it comes to the code challenges!!
