multipeerconnectivityのデータ送信ができない

Question

###前提・実現したいこと
multiprrrconnectivityを用いて簡単な２端末間でのクイズアプリを作っているのですが、senddataを用いて、データを送信したいのですが、データの送信は出来ているのですが、func session(session: MCSession, didReceiveData data: NSData, fromPeer peerID: MCPeerID) に届かないんです。

###該当のソースコード

   
    func session(session: MCSession, peer peerID: MCPeerID, didChangeState state: MCSessionState) {
        
    }
    func session(session: MCSession, didReceiveData data: NSData, fromPeer peerID: MCPeerID) {
        print("recivedata")

    }
    
    func session(session: MCSession, didReceiveStream stream: NSInputStream, withName streamName: String, fromPeer peerID: MCPeerID) {
    }
    
    func session(session: MCSession, didStartReceivingResourceWithName resourceName: String, fromPeer peerID: MCPeerID, withProgress progress: NSProgress) {
    }
    
    func session(session: MCSession, didFinishReceivingResourceWithName resourceName: String, fromPeer peerID: MCPeerID, atURL localURL: NSURL, withError error: NSError?) {
    }
    func send(){
        do{
            try appdelegate.session?.sendData(data, toPeers: (appdelegate.session?.connectedPeers)!, withMode: MCSessionSendDataMode.Unreliable)
            print("senddata")
        }
        catch{
            print("error")
        }
    }
    

func button1push(sender: UIButton){
        print("1push")
        if answer == "1"{
        self.view.backgroundColor = UIColor.redColor()
            image.alpha = 1
            image.image = imageo
            send()
        }
        else {
            self.view.backgroundColor = UIColor.blueColor()
            image.alpha = 1
            image.image = imagex
        }
    }

###試したこと
プログラムを実行してみると、デバックエリアにsenddataとは表示されますが、recivedataと表示されませんでした。

###補足情報(言語/FW/ツール等のバージョンなど)
seift2を使っています。

MCSessionDelegateはコードにありますか？

返信が遅れてすいませんMCSessionDelegateはclassに書いてあります。
