更新到Xcode 9.4之后，我开始收到一些错误，现在甚至无法构建它。这些错误是Apple Mach-o链接错误，dsymutil错误，同上错误。 dysmutil错误的详细信息如下；

clang: error: linker command failed with exit code 1 (use -v to see invocation)
我尝试了以下操作，但没有结果：（
1）清理并构建
2）启用位码：否
3）有效架构：删除arm7和arm64，仅删除armv7
4）吊舱更新
有帮助吗？

您是否尝试清除DerivedData文件夹？它位于/Users/Your_User/Library/Developer/Xcode/DerivedData中。之后，只需重新编译您的应用程序，然后查看它是否有效。
您还应该查找任何重复的文件，SDK，类，变量等。
如果这不起作用，并且您正在使用可可豆荚，则可以先运行pod cache clear，然后再运行pod install重新安装豆荚。
最后，如果这不起作用，并且您启用了源代码管理，则可以尝试删除本地副本，然后再次获取项目。

请共享您的Pod列表，其中一些具有双重info.plsit文件，这会在xcode 9中导致此问题，此外，请尝试转到“构建目录”并从此处删除info.plist，还有另一个问题。您正在使用什么设备和ios？

我创建了另一个项目，并将所有旧文件复制到新项目中。我已经安装了相同的广告连播。旧项目没有任何变化。现在可以了。
