Sway does not use d-bus. It listens on a unix socket (different from the wayland socket) for control messages. Gnome/Kde compositors don't use d-bus either, they instead use wayland extensions for control (since both the compositors and clients have to implement wayland already anyway, this is easier than using d-bus).
