根据经验，这可能是由于Apple Watch被iOS设备断开连接引起的。因此，可以尝试在应用程序中重新连接两者。以下是Swift语言的代码示例：

import WatchConnectivity

class InterfaceController: WKInterfaceController, WCSessionDelegate {
    
    var session: WCSession?
    
    override func awake(withContext context: Any?) {
        super.awake(withContext: context)
        
        if WCSession.isSupported() {
            session = WCSession.default
            session?.delegate = self
            session?.activate()
        }
    }
    
    func sessionDidBecomeInactive(_ session: WCSession) {
        // Do nothing
    }

    func sessionDidDeactivate(_ session: WCSession) {
        // Do nothing
    }

    func session(_ session: WCSession, activationDidCompleteWith activationState: WCSessionActivationState, error: Error?) {
        // Do nothing
    }
    
    func session(_ session: WCSession, didReceiveApplicationContext applicationContext: [String : Any]) {
        // Do something with the received data
    }
    
    func session(_ session: WCSession, didReceiveMessage message: [String : Any]) {
        // Do something with the received message
    }
    
    func startSession() {
        if session?.isReachable == true {
            // Session is already active, do nothing
        } else {
            session?.activate()
        }
    }
    
    func stopSession() {
        session?.deactivate()
    }
    
    override func willActivate() {
        super.willActivate()
        startSession()
    }
    
    override func didDeactivate() {
        super.didDeactivate()
        stopSession()
    }
}

这段代码创建了一个InterfaceController类，该类处理应用程序的界面以及与WatchConnectivity框架中的WCSession对象的通信。WCSession对象用于在iOS设备和Apple Watch之间传输数据。

在awake方法中，代码检查设备是否支持WCSession。如果是，它会创建
