PubNub 4.2.5 Swift Objective-C method: client: didReceiveStatus: 'conflict

Question

Я использую PubNub 4.2.5 на Swift IOS9.2 и получил это сообщение об ошибке conflude, любые идеи о том, как разрешить проблемы.

/Users/XXXX/xcode/XXXX/PubNub5/PubNub5/AppDelegate.swift:91:10: Objective-C method 'client:didReceiveStatus:' provided by method 'client(_:didReceiveStatus:)' conflicts with optional requirement method 'client(_:didReceiveStatus:)' in protocol 'PNObjectEventListener' 

Функция

//Handle subscription status change. 
    func client(client: PubNub!, didReceiveStatus status: PNSubscribeStatus) { 


    }

PubNub Подписаться IOS SDK Слушатель

Соответствующий класс должен быть PNSubscribeStatus.

Полный код подписки понравится, как в приведенном ниже коде. См. full docs for PubNub iOS Swift SDK v4.x subscribe API.

self.client?.subscribeToChannels(["my_channel1","my_channel2"], withPresence: false) 


// Handle new message from one of channels on which client has been subscribed. 
func client(client: PubNub!, didReceiveMessage message: PNMessageResult!) { 

    // Handle new message stored in message.data.message 
    if message.data.actualChannel != nil { 

     // Message has been received on channel group stored in 
     // message.data.subscribedChannel 
    } 
    else { 

     // Message has been received on channel stored in 
     // message.data.subscribedChannel 
    } 

    print("Received message: \(message.data.message) on channel " + 
       "\((message.data.actualChannel ?? message.data.subscribedChannel)!) at " + 
       "\(message.data.timetoken)") 
} 

// Handle subscription status change. 
func client(client: PubNub!, didReceiveStatus status: PNSubscribeStatus!) { 

    if status.category == .PNUnexpectedDisconnectCategory { 

     // This event happens when radio/connectivity is lost 
    } 
    else if status.category == .PNConnectedCategory { 

     // Connect event. You can do stuff like publish, and know you'll get it. 
     // Or just use the connected event to confirm you are subscribed for 
     // UI/internal notifications, etc 
    } 
    else if status.category == .PNReconnectedCategory { 

     // Happens as part of our regular operation. This event happens when 
     // radio/connectivity is lost, then regained. 
    } 
    else if status.category == .PNDecryptionErrorCategory { 

     // Handle messsage decryption error. Probably client configured to 
     // encrypt messages and on live data feed it received plain text. 
    } 
}
