Crash on subscribe in MQTT over web socket.

 public func write(_ data: Data, withTimeout timeout: TimeInterval, tag: Int) {
        internalQueue.async {
            let newWrite = WriteItem(tag: tag, timeout: (timeout > 0.0) ? .now() + timeout : .distantFuture)
            self.scheduledWrites.insert(newWrite)
            self.checkScheduledWrites()
            self.connection?.write(data: data) { possibleError in
                if let error = possibleError {
                    self.closeConnection(withError: error)
                } else {
                    guard self.scheduledWrites.remove(newWrite) != nil else { return }
                    guard let delegate = self.delegate else { return }

Bad Access occurred in self.scheduledWrites.insert(newWrite)
