What is wrong with todo.insert("Learn iOS", atIndex: 1) Note: This text box doesn't work well. Limits text.

var todo = ["Learn Swift", "Build App", "Deploy App"] todo += ["Debug App","Fix Bugs"] todo.removeAtIndex(4) let item: String = "Deploy App" todo.insert("Learn iOS", atIndex: 1)

The result is: ["Learn Swift", "Learn iOS", "Build App", "Deploy App", "Debug App"

Is that not correct?

Thanks, Tom

arrays.swift
var todo = ["Learn Swift", "Build App", "Deploy App"]
todo += ["Debug App","Fix Bugs"]
todo.removeAtIndex(4)
let item: String = "Deploy App"
todo.insert("Learn iOS", atIndex: 1)

I'm not quite clear what your question is, but the correct answer should look like this:

var todo = ["Learn Swift", "Build App", "Deploy App"]
todo.append("Debug App")
todo.append("Fix Bugs")
let item = todo.removeAtIndex(2)
todo.insert("Learn iOS", atIndex: 1)
