删除派生数据为我保存了它

我遇到了同样的问题，但公认的解决方案并不适合我。相反，解决方案是修改框架的安装名称。

原帖子中的错误是:

dyld: Library not loaded: /Library/Frameworks/TestMacFramework.framework/Versions/A/TestMacFramework
  Referenced from: /Users/samharman/Library/Developer/Xcode/DerivedData/TestMacContainer-dzabuelobzfknafuhmgooqhqrgzl/Build/Products/Debug/TestMacContainer.app/Contents/MacOS/TestMacContainer
  Reason: image not found

注意Library未加载后的第一个路径。框架是从绝对路径加载的。这个路径来自框架的安装名(有时称为rpath)，可以使用以下方法检查:

otool -D MyFramework.framework/MyFramework

当一个框架被嵌入到一个应用程序中时，这个路径应该是相对的，并且是这样的形式:@rpath/MyFramework.framework/MyFramework。如果你的框架的安装名称是一个绝对路径，它可能不会在运行时被加载，并且会产生类似上面的错误。

解决方案是修改安装名称:

install_name_tool -id "@rpath/MyFramework.framework/MyFramework" MyFramework.framework/MyFramework 

有了这个更改，我不再得到错误

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!

I found that this issue was related only to the code signing and certificates not the code itself. To verify this, create the basic single view app and try to run it without any changes to your device. If you see the same error type this shows your code is fine. Like me you will find that your certificates are invalid. Download all again and fix any expired ones. Then when you get the basic app to not report the error try your app again after exiting Xcode and perhaps restarting your mac for good measure. That finally put this nightmare to an end. Most likely this has nothing to do with your code especially if you get Build Successful message when you try to run it. FYI

当尝试Xcode 9测试版并返回到Xcode 8时，出现了问题。对目标进行简单的Clean就解决了这个问题。
