I was not taught this and the functions I know are not working.

It is asking mer to print out the number of items in array "todo" using the ".count" function and println. I know println and wrote:

var todo = ["Lear Swift","Build App","Deploy App"]

print; todo.count

that didn't work so I did this:

var todo = ["Lear Swift","Build App","Deploy App"]

var todoNum = todo.count

println; todoNum

This worked in Xcode and printed the number I was looking for but the workspace challenge keeps telling me I'm wrong.

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

todo.count

println; 3

Oh so close! Remember in println we say println and then what we want to print. I'm not sure where your semicolon is coming from :smiley: Take a look:

var todo = ["Learn Swift", "Build App", "Deploy App"]
println(todo.count)
