We need to append a few more items to our todo array. Append the following strings: "Debug App", "Fix Bugs".

What am I doing wrong?

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

Hi, John Moron , if you wanna append everything in one line, then change your last line to

todo += ["Debug App","Fix Bugs"]

with +=, you can merge two list into one.

There are a few different ways to do this but one you can try is to append them one at a time.

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