我正在开发Safari应用程序扩展。以前它运行良好。当我在Xcode中运行项目，并在Safari中启用允许无符号扩展时，我可以在Safari Preferences->Extensions页面中看到我的扩展。
在我将代码与我的一名团队成员合并后，扩展突然无法安装。
我试过：
- 清理Xcode中的构建文件夹，然后再次运行。但运气不好
- 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。我的分机不在名单上
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.

现在我没有选择了。它在苹果开发者网站上缺乏官方文档。
是否有常规步骤来解决此类问题？有什么类型的系统日志可以帮助我解决错误吗？欢迎提出任何建议。
确保扩展.appex列为应用程序扩展目标的嵌入内容。否则，当您从Xcode构建时，它就不会被捆绑。在项目编辑器中的Target_Name>General>Frameworks，Libraries and Embedded Content下查找。扩展名应该列在那里。
还要检查"构建阶段"选项卡>"依赖项"下是否也添加了扩展。
检查应用程序的代码签名是否有效。Safari将拒绝列出您的扩展。在您构建的应用程序上运行codesign，如下所示：
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，即使启用了Allow Unsigned Extensions。
我最近在更新到Xcode 13.2.1和MacOS更新后遇到了类似的问题。我正在开发的Safari网络扩展已停止显示在Safari中(即使启用了未签名的扩展(。
在Terminal/CLI shell中，我最终运行了：
PATH=/System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support:"$PATH"
lsregister -f /Applications/Safari.app
突然间，我的扩展再次出现在Safari中。Safari和LaunchServices发生了一些奇怪的事情。
