[swift-users] CustomStringConvertible?

[Joanna Carter]

Greetings

> Thanks for your reply, Rien. I just tried this again, and now it seems that either is acceptable. Seems a little weird, but I guess I’d rather have more flexibility than less.

>     var description:String = "I am a GPS"

You can also implement description as a let, since there is no intention to modify it :

class GPS : Powerable, CustomStringConvertible
{
  let description = "I am a GPS"
  
  …
}
