Challenge Task 2 of 2 is giving me an error. Why? println("\(todo.count)") will indeed give me the number of items.

When I insert this code into my own playground I get the correct answer: 3

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

Hi Randolph,

Because interpolation isn't absolutely necessary (the argument you're aiming to print is numerical), the code challenge doesn't seem to be expecting it (even if it would otherwise work.)

println(todo.count)

Hope this helps!

Thanks, CJ. That did the trick.
