What does Observable protocol (not macro) conformance get you? (Unrelated to TCA - please excuse)

[bitsarat]

Hi, In the Apple Scrumdinger sample, the SpeechRecognizer class conforms to the Observable protocol:

public actor SpeechRecognizer: Observable {
    public enum RecognizerError: Error {
        case nilRecognizer
.
.
.

developer help text suggests that the protocol conformance does not add observation functionality. This class does not use the @Observable macro. So, how does this work under the hood?

Hi @bitsarat, that conformance is not needed at all. You can remove it and it will still compile and work the same.

Thanks Brandon!
