所以背景是这样的：我有一个 Xcode 项目，它依赖于 github 上私有存储库中的 swift 包。当然，这需要密钥才能访问。到目前为止，我已经设法配置 CI，以便我可以 ssh 进入实例和git cloneswift 包所需的存储库。不幸的是，当xcbuild像 CI 一样运行它时，它不起作用，我收到以下消息：
static:ios distiller$ xcodebuild -showBuildSettings -workspace ./Project.xcworkspace \
-scheme App\ Prod

xcodebuild: error: Could not resolve package dependencies:

static:ios distiller$ git clone git@github.com:company-uk/ProjectDependency.git
