amit types 

let cards = 1...13

using the ... syntax creates a range, so cards is a constant of type range.

Hey Jeremy,

that isn't valid swift code, nor would something like this ,

let cards

if you do what you said Xcode says "expecting initial value after '=' ". so I'm not sure what you means because the code you said ins't valid.

Best, Kai

Ok as stone says, the 1...13 make a range.

In Xcode, if you hold option and click on where you declare "cards", it will tell you:

declaration: let cards = Range<Int>

So, the type would be a range, specifically a range of integers.
