Array

Hello,

How can I print out the number of items in the todo array using println? I know for counting I need to write for example: todo. count, but it does not work.

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

The println function prints the value as a string.

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

println(todo.count)

Remember that the ebook "The Swift Programming Language" by Apple is a great (and free) resource on Swift, and you can learn a lot just by skimming through the first chapter.
