Question

我正在尝试在Apple Watch上启动HKWorkoutSession，并将心率数据即时发送到iPhone以进行近乎实时的显示。为实现这一目标，我正在使用WatchConnectivity的sendMessage方法。我不需要来自手机/手表的回复，所以我使用的是不使用回复处理程序的sendMessage版本。

心率数据没有进入手机，我很难理解为什么。我没有得到任何有用的错误消息。我怎么知道出了什么问题？我已经将手机应用程序和手表应用程序连接到调试器，但由于消息永远不会到达手机，我在查明正在发生的事情时遇到了很多麻烦，因为很明显我的电话代码中的断点不是到达。之前，我使用的是sendMessage的replyHandler版本，它有一个用于错误处理的闭包。使用它，我能够看到我的错误（有时）是由于收到返回消息的超时。但是，手机上的didReceiveMessage代表从未到过，所以我从未发送过它的回复信息，我并不感到惊讶。我假设手机应用和手表应用之间的连接有问题，但我检查了isReachable布尔值，以及isPaired和isWatchAppInstalled。

所以我想我想知道你是否有关于Watch Connectivity调试技术的任何提示。而且，如果你想看看我的代码，也就是这样。如果你看到任何明显的错误，请告诉我。（对不起，它有点草率 - 只是试着让事情立即发挥作用。）
