println issue in array challenge

How can I get past this issue with Swift Basics - Arrays - Challenge - Task 2 of 2 The challenge states to use the println statement which is not supported in Xcode 7. It compiles and works in Xcode but the challenge cannot be completed because I din't use println.

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

Hi there,

My Xcode 7 works fine with println. I think the method is deprecated, not illegal.

I don't think the compiler behind the challenge is updated yet, so print probably won't work. But println will. Do bear in mind that the tests behind the challenge are expecting to see a simple output - 3 - not a long string.

So, the final line of the challenge needs to be:

println(todo.count)

Hope that helps.

Steve.

Thanks, guess I was overthinking the challenge. In the playground in Xcode, if I type println I immediately get an error and says to change to print.

How strange - I get no errors but I may have turned such things off a while ago!

In each challenge just do exactly what it asks; don't even replicate what the previous video had you do. The questions are asked in their entirety and there's no points for any extras!

I hope you make good progress and if you run into any difficulties, just shout in here!

Steve.
