Question

我正在开发Safari应用程序扩展。以前它工作正常。当我在Xcode中运行项目并在Safari中启用允许未签名的扩展时，我可以在 Safari偏好设置->扩展页面中看到我的扩展。

我与团队成员之一合并代码后，突然无法安装扩展程序。

我尝试过：

在Xcode中清洁build文件夹，然后再次运行。但没有运气。
重启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。我的扩展名不在列表中。

Xcode输出中存在一些错误，但是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.

One of the two will be used. Which one is undefined.

现在我已经用完了所有选项。它缺少Apple Developer网站上的官方文档。

是否有常规步骤来解决此类问题？是否有任何系统日志可以帮助我解决错误？任何建议表示赞赏。

Answer 1

检查您应用的代码签名是否有效。 Safari否则将拒绝列出您的扩展名。在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。否则，即使启用Allow Unsigned Extensions，Safari也将完全忽略您的扩展名。

Answer 2

确保扩展.appex被列为您的App Extension目标的嵌入式内容。否则，当您从Xcode构建时，它不会被捆绑。在项目编辑器中的“目标名称>常规>框架，库和嵌入式内容”下查找。该扩展名应在此处列出。

还要检查“构建阶段”选项卡下的>依赖项，也将扩展名也添加到那里。

当Safari应用程序扩展未出现在Safari首选项中时，如何解决？
