I've also fixed this issue by going to Product -> Clean in XCode. This might erase the files in the files in the Derived Data folder in the process.
我还通过转到 XCode 中的 Product -> Clean 解决了这个问题。这可能会在此过程中删除派生数据文件夹中文件中的文件。

Maybe double-check the Xcodefile you are running. Close the Xcodeproject then be sure to open the <projectname>.xcworkspacefile.
也许仔细检查Xcode您正在运行的文件。关闭Xcode项目然后确保打开<projectname>.xcworkspace文件。
If you are using cocoapods, the error can be from trying to build from the .xcodeprojfile instead of the .xcworkspacefile generated by the pod install.
如果您使用的是cocoapods，则错误可能是由于尝试从该.xcodeproj文件而不是.xcworkspace由 pod 安装生成的文件进行构建。
