Im Stuck on Swift Basics Collections

I'm trying to print out todo but I am having problems doing that. It also says that I need to use todo.count, but I don't know why.

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

todo.count

println\(todo)

I believe you would just need to print out the array like this

println(todo)

The key to solving this is using Loops, perhaps re-watch those videos. Here is an example of looping over the array and printing each item:

for item in todo {
   println("Current Item => \(item)")
}

To use todo.count you will need to create a for loop with a counter.

Hey simondumalski,

Your answer is really close. All you need to do is directly print "todo.count", not just call it in the previous line. println works for both numbers and strings.
