raop 服务能够连接，并且我的应用似乎正在接收来自 iOS 的流。
以下是配置服务的代码：
airplayService = NetService(domain: "local", type: "_airplay._tcp", name: serviceName, port: 7000)
airplayService?.delegate = self
airplayService?.startMonitoring()
airplayService?.publish(options: NetService.Options.listenForConnections)
airplayService?.setTXTRecord(NetService.data(fromTXTRecord: [

我在这个错误上找不到任何东西。这是什么意思？我的 txt 记录中是否有需要更改的特定内容？
