 1. `socket.on(name:String, callback:((data:NSArray?, ack:AckEmitter?) -> Void))` - Adds a handler for an event. Items are passed by an array. `ack` can be used to send an ack when one is requested. See example.
 2. `socket.onAny(callback:((event:String, items:AnyObject?)) -> Void)` - Adds a handler for all events. It will be called on any received event.
 3. `socket.emit(event:String, args:AnyObject...)` - Sends a message. Can send multiple args.
-4. `socket.emitWithAck(event:String, args:AnyObject...) -> SocketAckHandler` - Sends a message that requests an acknowledgement from the server. Returns a SocketAckHandler which you can use to add an onAck handler. See example.
-5. `socket.connect()` - Establishes a connection to the server. A "connect" event is fired upon successful connection.
-6. `socket.connectWithParams(params:[String: AnyObject])` - Establishes a connection to the server passing the specified params. A "connect" event is fired upon successful connection.
-7. `socket.close()` - Closes the socket. Once a socket is closed it should not be reopened.
+4. `socket.emitObjc(event:String, args:[AnyObject])` - `emit` for Objective-C
+5. `socket.emitWithAck(event:String, args:AnyObject...) -> SocketAckHandler` - Sends a message that requests an acknowledgement from the server. Returns a SocketAckHandler which you can use to add an onAck handler. See example.
+6. `socket.emitWithAckObjc(event:String, _ args:[AnyObject]) -> SocketAckHandler` - `emitWithAck` for Objective-C.
+7. `socket.connect()` - Establishes a connection to the server. A "connect" event is fired upon successful connection.
+8. `socket.connectWithParams(params:[String: AnyObject])` - Establishes a connection to the server passing the specified params. A "connect" event is fired upon successful connection.
