What's wrong with this append code?

Trying to figure out why this challenge is throwing an error for the following code.

todo.append("Debug App")

I'm try to append the following list:

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

with todo.append("Debug App"). Seems to work fine in Xcode but when I try to do this on challenge it is saying I have the wrong value(???).

var todo = ["Learn Swift", "Build App", "Deploy App"]
todo.append("Debug App")

Hi Varghese,

The task asks you to append 2 items which are Debug App and Fix Bugs, the code you should have is as follows.

todo.append("Debug App")
todo.append("Fix Bugs")

Happy coding!

Thank Chris. That worked. I got hung up on the error message and failed to try to add two appends consecutively.
