Whats the difference between an enum's stored property's default value and rawValue?

For example:

enum HTTPStatusCodes: Int {

case Continue = 100
case Success = 200
case Unauthorized = 401
case Forbidden = 403
case NotFound = 404

} case Continue = 100 is both a rawValue and default value?

They are the same.

Apple documentation: "enumeration cases can come prepopulated with default values (called raw values), which are all of the same type."

Hi there is no difference at all.

Enum Members can have default values which are known as raw values. Raw values can only be certain types. These types include strings, Integers, Characters and Floating point Numbers.

Associated values are set when you create an enum and they can be different values for every instance including custom types.
