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。

下面是正确设置的截图: 希望这能有所帮助!

删除派生数据为我保存了它

对于Xcode 8，一些陈旧的产品将从派生的数据文件夹中删除参考这个解决方案。

苹果:在macOS 10.12及以后版本中，Xcode会清理陈旧的派生数据、预编译的头文件和模块缓存。(23282174)

Xcode构建系统支持旧文件删除某些类型的构建构件，这些构件在以前的构建中产生，但已经从项目中删除了。

根据作者的想法，我从我的案例中找到了这个构建日志。

Remove stale build products

/bin/rm -rf /Users/usename/Library/Developer/Xcode/DerivedData/myapp-esvvhwwwwngijeemhatmklwzoxnb/Build/Products/Debug-iphonesimulator/myapp.app/Frameworks/AliyunVodPlayerSDK.framework
/bin/rmdir /Users/usename/Library/Developer/Xcode/DerivedData/myapp-esvvhwwwwngijeemhatmklwzoxnb/Build/Products/Debug-iphonesimulator/myapp.app/Frameworks

在创建新的复制文件阶段并将目标陈旧框架复制到框架目标之后，上述删除日志在重建后消失。

澄清一下我的情况和原因，希望对大家有所帮助。

对我来说，这就是解决方案，经过许多小时的搜索!!

出于某种原因，在Swift 2.3自定义框架的开发过程中，Xcode 8从项目中删除了DYLIB_INSTALL_NAME_BASE设置。pbxproj文件。稍微进入Build Settings / Dynamic Library Install Name Base设置回到@rpath就修复了它。

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。

上面的选项对我来说不可能包括。 我通过指定Runpath搜索路径来解决这个问题

这是在“构建设置”选项卡上。 在“链接”部分。 将“Runpath Search Paths”更改为$(inherited) @executable_path/Frameworks
