解决 Xcode12+swift 5 使用 pod 出现警告的问题

起因

在新建项目后，使用 pod 安装一些组件，结果出现了如下错误

Pod installation complete! There is 1 dependency from the Podfile and 1 total pod installed.

[!] The `bestWhiteNoise [Debug]` target overrides the `ALWAYS_EMBED_SWIFT_STANDARD_LIBRARIES` build setting defined in `Pods/Target Support Files/Pods-bestWhiteNoise/Pods-bestWhiteNoise.debug.xcconfig'. This can lead to problems with the CocoaPods installation
    - Use the `$(inherited)` flag, or
    - Remove the build settings from the target.

[!] The `bestWhiteNoise [Release]` target overrides the `ALWAYS_EMBED_SWIFT_STANDARD_LIBRARIES` build setting defined in `Pods/Target Support Files/Pods-bestWhiteNoise/Pods-bestWhiteNoise.release.xcconfig'. This can lead to problems with the CocoaPods installation
    - Use the `$(inherited)` flag, or
    - Remove the build settings from the target.

This can lead to problems with the CocoaPods installation

    - Remove the build settings from the target.

查询了一些文档后，发现是我们项目中的设置 和 Pods 中的设置不一致，并且显示的是警告，实际上是错误，可能会导致你的第三方组件安装不成功等问题

解决方案

看了很多文章，都是搜索 ALWAYS_EMBED_SWIFT_STANDARD_LIBRARIES 设置成 $(inherited)，但是没有细说需要设置哪几个地方，可能对于我这种新手来说就是一个坑，实际上我们需要设置每一个 TARGETS 中的 ALWAYS_EMBED_SWIFT_STANDARD_LIBRARIES 为 $(inherited)

如图：

保存，然后 TARGETS 中的每一个，比如我图片中的三个，那么这三个我都需要设置

设置完后，再次运行 pod install 就好了
