It is also integrated with AppleWatch, so you can control the slides from your wrist.

Requirements

• iOS 8.0+ (Apple Watch & Keynote presentations support - iOS 9.0+)

Get Started

SmartSlides workflow mechanism is based on Apple MultipeerConnectivity framework. Managing advertiser & browsing functionality implemented in AdvertisingManager & BrowsingManager classes.

For example, creating advertising session workhorse method:

    func createPresentationSessionWithName(name : String) {
        let presentationSession = PresentationSession(peer: MCPeerID(displayName: name), serviceType: kServiceTypeName, delegate:     handler, index: 0, creationDate: NSDate(), broadcastingDevice: UIDevice().model)
        
        sessions.append(presentationSession)
        
        isActive = true
        delegate?.connectivityManagerDidChangeState(self)
    }

Creating browsing session:

    func instantiateObserverSessionWithName(name : String, browsingDelegate delegate : BrowsingHandlerDelegate?) {
        browsingSession = MCSession(peer : MCPeerID(displayName: name), securityIdentity : nil, encryptionPreference: .None)
        handler = BrowsingHandler(browsingDelegate: delegate)
        (handler as! BrowsingHandler).connectivityDelegate = connectivityDelegate
        browsingSession!.delegate = handler
    }

Both AdvertisingManager & BrowsingManager callbacks handling incapsulated in SessionHandler child classes - AdvertiserHandler & BrowsingHandler. These classes handle receiving messages data between peers, monitoring connection state & files transfering progress. Messaging between peers is also incapsulated via SessionCommand classes. Each message type, data transfers actions should be encapsulated in specific class, SessionCommand inheriter.

Simple ping message sending & receiving command class example:

    class CommandPing: SessionCommand {

        required init(parameters: [String : String]) {}
        
        func execute(session: MCSession, peers: [MCPeerID]) -> (Bool) {
            AppDelegate.shared.browsingManager.backPingMessageReceived()
            return true
        }
    }
    
    
    class CommandGetPing: SessionCommand{
        required init(parameters: [String : String]) { }
        
        func execute(session: MCSession, peers: [MCPeerID]) -> (Bool) {
            do {
                print("Ping received, ping sent back")
                try session.sendData(SessionHandler.dataRequestForCommandType(.PingServer, parameters: nil), toPeers: peers, withMode: .Reliable)
                return true
            } catch let error as NSError {
                print("Error sending ping: \(error)")
                return false
            }
        }
    }

Presentation files can be provided by Dropbox (just create app page on [Dropbox] (https://www.dropbox.com/developers) and add key & secret string in AppDelegate), Mail app attachments and also 2 presentation files are already presented in the app by default
