对我来说，由于某种原因xCode(到目前为止12.5)决定我的通知服务扩展目标不应该有正确的框架路径。我怀疑这发生在我从xCode 12.1更新到12.5之后。

所以我得到了与我的一个内部框架相关的相同错误。要解决这个问题，请执行以下操作:

go to Project's General Tab Select your target (in my case it was Notification Service Extension Target) Make sure that Framework and Libraries section contains your missing framework. I've left it Embed Without Signing in my NSE Target, but it is also was added with Embed & Sign to my primary app target Keep your target selected and switch to Build Settings tab There in a search bar enter LD_RUNPATH_SEARCH_PATHS (make sure that All possible settings will be displayed and not just Basic) You will see Runpath Search Paths and it was empty for me. Add 3 following values there: $(inherited) @executable_path/Frameworks @executable_path/../../Frameworks

这对我很有帮助。

[Xcode 11 +]

唯一要做的就是将框架添加到目标应用程序的General选项卡中的General->Frameworks, Libraries And Embedded Content部分。

确保你选择了“嵌入&签名”选项。

[Xcode v6 -> Xcode v10]

唯一要做的就是将框架添加到目标应用程序General选项卡的Embedded binaries部分。

我尝试了许多修复，但对我有效的是删除构建方案的构建选项卡中列出的缺失目标。您可以通过打开当前方案的编辑窗口来访问它。

编辑:我的UI测试目标不能正常工作，我找到的解决方案是删除它并重新生成它。

Xcode 11: 构建阶段->嵌入框架

我在Xcode 13 beta版中使用uniformtypeidentifier .framework遇到了这个问题。该应用程序无法在低于13的iOS版本上运行。 下面的方法解决了这个问题:

去目标->构建阶段->链接二进制与库->添加框架->添加状态为“可选” 以上方法对我来说非常有效!希望这能有所帮助!

None of these issues solved this for me. The problem in the end was pretty easy. It looks like its a pretty major Xcode bug which I have logged the problem and fix under Apple bug: 29820370. If you are struggling (as it seems like there are several pages of problems similar to this ) then it would be great if you can raise a bug on bug reporter: https://bugreport.apple.com/ and reference the bug I raised to gain visibility. I want to make Xcode back into the pleasure that it was before - and this is something I am sure Xcode should have fixed itself.

下面是解决方案: 1. 打开钥匙串-去苹果全球开发者证书。 2. 双击它 3.将权限级别从“始终信任”更改为使用“系统默认” 4. 保存并关闭 5. 重新启动Xcode，清理并构建项目，它应该消失了。
