Help!

it looks fine but it keeps saying your todo variable has the wrong value in it ? what does that mean

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

Hello :

When using the append method, you should only add one item at a time.

Now if you want to add one or more items to the array, you can use the += operator. 

todo += ["Answer questions","Master Swift","Create an app"]

Keep going, it gets better :)

Since you want to add two items to the array I would use the addition assignment operator (+=). This is used if you want to add more than one compatible item to the array.

Try the code below:

var todo = ["Learn Swift", "Build App", "Deploy App"] todo =+["Debug App", "Fix bugs"]

Note that you use brackets with the addition assignment operator and not parenthesis. Hope this helps, Mindy
