我正在开发一个 Safari 应用程序扩展。以前它工作得很好。当我在 Xcode 中运行项目并在 Safari 中启用Allow Unsigned Extensions时，我可以在Safari Preferences -> Extensions页面中看到我的扩展。

在我与我的一位团队成员合并代码后，突然无法安装扩展。

我努力了：

  • 清理 Xcode 中的 build 文件夹，然后再次运行。但没有运气。
  • 重新启动 Xcode 也无济于事。
  • 使用命令pluginkit -mAvvv -p com.apple.Safari.extension检查已安装的 Safari 扩展列表。我的分机不在列表中。

Xcode 输出中有一些错误，但我无法将它们与我面临的问题联系起来：

objc[49476]: Class AMSupportURLConnectionDelegate is implemented in both /System/Library/PrivateFrameworks/EmbeddedOSInstall.framework/Versions/A/EmbeddedOSInstall (0x7fff9a2aa748) and /System/Library/PrivateFrameworks/MobileDevice.framework/Versions/A/MobileDevice (0x108db2600). One of the two will be used. Which one is undefined.

现在我的选择已经不多了。它在 Apple Developer 网站中缺少官方文档。

是否有解决此类问题的常规步骤？是否有任何类型的系统日志可以帮助我解决错误？任何建议表示赞赏。

确保扩展.appex被列为您的应用扩展目标的嵌入内容。否则，当您从 Xcode 构建时，它不会被捆绑。查看 Target_Name > General > Frameworks, Libraries and Embedded Content 下的项目编辑器。扩展名应该列在那里。

还要在 Build Phases 选项卡 > Dependencies 下检查您的扩展是否也添加到了那里。

检查您的应用程序的代码签名是否有效。否则 Safari 将拒绝列出您的扩展程序。在您构建的应用程序上运行codesign如下：

codesign -d --verify --verbose=3 ~/Library/Developer/Xcode/DerivedData/OnePassword-epeydspviethpabprcrsqenrkiin/Build/Products/Debug_WebStore/1Password\ 7.app

它应该显示valid on disk和satisfies its Designated Requirement。如果没有，Safari 将完全忽略您的扩展程序，即使Allow Unsigned Extensions已启用。

在更新到 Xcode 13.2.1 和我认为是 MacOS 更新后，我最近遇到了类似的问题。我正在开发的 Safari Web 扩展停止显示在 Safari 中（即使启用了未签名的扩展）。

在终端/CLI shell 中，我最终运行：

PATH=/System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support:"$PATH"
lsregister -f /Applications/Safari.app

突然间，我的扩展又开始出现在 Safari 中。Safari 和 LaunchServices 发生了一些奇怪的事情。
