Proto3 Optional fields should be Swift optionals #1114
Description
I see that there is support for Proto3 optionals (#1096) however as far as I can tell the generated code does not actually expose these as Swift optionals:
public var email: String {
get {return _email ?? String()}
set {_email = newValue}
}
/// Returns true if `email` has been explicitly set.
public var hasEmail: Bool {return self._email != nil}
/// Clears the value of `email`. Subsequent reads from it will return its default value.
public mutating func clearEmail() {self._email = nil}This seems to defeat a lot of the ergonomics that would be possible if these came through directly as Swift optionals. If there's some backwards compatibility issues, I'm happy to enable some flag for it.
