iOS Swift Basics (retired) Collections What is an Array?

It wants me to do a count on the items in the lists and when I do that and hit Recheck work it says bummer try again.

I made the list, did the println("todo"), then it wants me to do the count so I did then when i check work it just says Bummer! Try again! nothing else and no errors

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

Hey Samuel,

The second part of the challenge wants you to "Print out the number of items in the todo array using println."

Right now, you are only printing the string "todo". And the last line of code is just dangling there. You just need to move the todo.count into the println method to print the count.

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

Hope that helps to make sense. Keep Coding! :)


OHHHH, dang it...Thank you very much i'll remember that from now on!

I'd recommend you take the Swift 2.0 course. Theres no point in learning outdated material. for instance, println doesnt even exist anymore. Its now just "print".

Swift is a new language and is thus rapidly evolving with major changes. 3.0 will be out soon, and even more of Swift 1.0 will be outdated

I will take a look at it then for sure. Thank you and I appreciate the help!
