Hi Michael,

with append you can only add one object to an array. To add more objects you can use the "+=" operator or the .extends method. Take a look at the documentation of Apple for collection types.

Here is your example working in playground:

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