everytime I put dot count it would give me error and says you need to use println() but I don't how to

Hello Michael, All you need to do is type println() into your code and put todo.count within the parentheses. Your code should look like this...
var todo = ["Learn Swift","Build App","Deploy App"]
Let me know if this helps :)
