So the problem is to insert a number onto the second postion of the array. Here's a solution using the (_: insertAt) array method 

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

print(todo)  // prints [Learn Swift, test, Build App, Debug App, Fix Bugs]

I hope I've helped. Happy Coding! :)
