Print & Creating a List Question

The following is my code:

print("List: \n 1 \t Apple \n 2 \t Bananas \n 3 \t Oranges")

Results: The list is created

Problems:

  1. I noticed now an error comes up when try to use println. It is telling me to use just print.

  2. The list is not lined up in the left hand side.

What changed: I read on Google that Swift 2.0 just uses print() and not println() - not sure if this is correct. Also I did upgrade xcode to 7.2

Thank you for your help Fred

Fred,

Starting in Swift 2.0, the print function changed to just "print" as opposed to "println". You can find a little more info on this at the link below.

In swift 2.0 the print statement is just print() not println(). For the alignement problem you can just use concatenation or set var or constants then wrote code or use a while loop.

let list = ["apple", "fruit", "candy"] let i = 0 while (i < list) { print(list[i]) ++i }
