I used the code println("\(todo) \(todo.count)") and all it keeps telling me is bummer what am I missing with my code

I just want to make sure that I am doing this right

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

task 2 states: Print out the number of items in the todo array using println.

you wrote

println("\(todo) \(todo.count)")

However, all it wants its the count to be printed, not the todo array AND the count (note: since you are just printing the array count by itself interpolation is not necessary)

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

you generally have to follow the instructions very carefully. If you provide something the challenge did not ask for, it wont let you pass.

var countries = ["Zimbabwe","Zambia","Malawi"]

println(countries.count)//this will print the number of items in the array
