Error in errata?

In the notes on changes caused by Swift 2.0, the change for pg.123 says:

let attributes = NSSpeechSynthesizer.attributesForVoice(voice) return attributes[NSVoiceName] as? String

But the parameter passed to the voiceNameForIdentifier(_:slight_smile: function in the book is ‘identifier’. So shouldn’t it be:

func voiceNameForIdentifier(identifier: String) -> String? { let attributes = NSSpeechSynthesizer.attributesForVoice(identifier) return attributes[NSVoiceName] as? String }

Where did you read this?

I read it too. It is on this page: … /

Is that page the wrong page for the book’s errata?
