无法将 WatchOS 目标添加到 React Native App

Question

我开发了几个手表应用程序并且我已经掌握了它，但是当我尝试将 watch os 目标添加到 React Native 应用程序时，我遇到了 47 个我不明白的错误。

我正在尝试遵循本教程 - 如何向您的本机应用程序添加 Apple Watch 扩展。

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

然后我可以构建和运行该项目。（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。此时 React Native 应用程序从 xCode 构建和运行也没有问题。

在工作区中，我选择主项目并单击+下方的目标。

从这里我选择watchOS和Watch App for iOS App：

使用以下设置：

当被问到时，我激活了目标：

并创建了目标。

6. 运行观察目标

这是问题开始浮出水面的地方。我注意到的第一件事WatchApp Extension是在创建目标之后有一个错误：

编译 Swift Sources 有什么问题吗？

如果我尝试WatchApp在模拟器中运行目标，我会收到 47 个错误：

如何解决这些错误并Hello World使用 React Native 和 Apple Watch运行基本程序？

Answer 1

当我遇到这个时，@Tabbyofjudah 建议的路径已经出现在列表中，

我实际上通过删除watchOS 扩展的库搜索路径的内容来解决这个问题。让它看起来像这样：

我的项目现在构建（不仅仅是作为一个bodge，一直到App Store Connect）。希望这对某人有用。

Answer 2

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，选择 Watch Extension Target，然后选择 Build Settings Menu，并找到Library Search Paths设置。（您需要确保选择了“全部”过滤器，否则您将看不到此设置）。在它的值中，您将看到两个链接，仅使用第一个...将 ov Library Search Paths值设置为："$(TOOLCHAIN_DIR)/usr/lib/swift/$(PLATFORM_NAME)"

这对我有用
