Seemingly-bogus error message when overriding a var

[Jens Alfke]

I’ve got a variable with a public getter and internal setter, and I override it in a subclass but get an error complaining about the accessibility of the setter. This doesn’t make sense because the access control in the override is identical. If I take out “internal (set)”, to make the setter public, the error goes away; but I don’t want the setter to be public. What’s going on here?

(Xcode 7 beta 3)

public class Peer : NSObject {

    public internal(set) dynamic var online = false

}

public class OnlinePeer : Peer, NSNetServiceDelegate {

    public internal(set) override dynamic var online: Bool { … }

}

The error is:

Peer.swift:52:47: error: setter of overriding var must be as accessible as the declaration it overrides

    public internal(set) override dynamic var online: Bool

           ~~~~~~~~~~~~~~                     ^

           

Peer.swift:32:38: note: overridden declaration is here

    public internal(set) dynamic var online = false
