Hello Michel:

Using the arrays method called “count”, can help you get the number of the items in the array, combining this with the println() method will print what you need.

You access this method with the . syntax.

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


println(todo.count) // will print 3
