Try this:

Println(todo[2])

Note that your array has 3 strings, ur first string is indexed at 0 then 1 then 2

Println(3) is only printing out the Int 3 into the console...

It looks like you're doing the "print the number of items in the array" challenge - is that right?

If so, the problem is that I believe that the challenge looks to see that you're correctly doing the challenge, not just that you get the right answer.

In other words, even though "3" is the correct answer, you're not getting it the correct way.

Here is my suggestion to fix your code - note the comment below:

var todo: [String] = ["Learn Swift", "Build App", "Deploy App"]
println(todo.count)   // this prints out a 3 because there are 3 items in the array
