无法将 WatchOS 目标添加到 React Native App
Cannot add WatchOS target to React Native App
我已经开发了几个手表应用程序并且我正在掌握它，但是当我尝试将手表 os 目标添加到 React Native 应用程序时，我收到 47 个我不明白的错误.
我正在尝试关注此 tutorial - How to add an Apple Watch Extension To your react native application。
重现步骤
1。创建一个新的 React Native 项目
首先，我创建了一个新的 React Native 项目。 （成功✅）
react-native init RNWithAppleWatch
2。构建并 运行 React Native 项目
然后我可以构建 运行 项目。 （成功✅）
cd RNWtihAppleWatch; npm run ios;
3。打开项目工作区并添加一个目标
接下来，我打开工作区文件。在这一点上，React Native 应用程序从 xCode 构建和 运行s 也没有问题。
在工作区内，我 select 主项目并单击目标下的 +。
从这里我 select watchOS 和 Watch App for iOS App:
具有以下设置：
当被问到时我激活了目标：
目标已创建。
6. 运行 监视目标
这就是问题开始浮出水面的地方。我注意到的第一件事是创建目标后 WatchApp Extension 中有一个错误：
编译 Swift 源代码时出现某种问题？
如果我尝试 运行 模拟器中的 WatchApp 目标，我会收到 47 个错误：
我如何解决这些错误以及如何使用 React Native 和 Apple Watch 运行 基本 Hello World？

我能够通过更改 库搜索路径 构建设置来解决此问题。
在您的项目中 select Watch Extension Target，然后是 Build Settings Menu，然后找到 Library Search Paths 设置。 （您需要确保“全部”过滤器已 selected 否则您将看不到此设置）。在它的值中，您会看到两个链接，仅使用第一个链接...将值 ov Library Search Paths 设置为："$(TOOLCHAIN_DIR)/usr/lib/swift/$(PLATFORM_NAME)"
这对我有用
当我遇到这个时，@Tabbyofjudah 建议的路径已经存在于列表中，
我实际上通过删除 watchOS 扩展的库搜索路径的内容解决了这个问题。让它看起来像这样：
现在我的项目正在构建（不只是作为一个障碍物，一直到 App Store Connect）。希望这对某人有用。
