ios - Apple Mach-O 链接器错误。链接器命令失败，退出代码为 1

Question

我的应用程序在过去几天运行良好，但突然出现此错误。

我已经尝试过这些事情:

• 重新启动 Xcode 和 Mac
• 清洁项目
• 清理派生数据文件夹

这里是错误:

clang: error: linker command failed with exit code 1 (use -v to see invocation)

这里还有一个警告

ld: warning: linking against dylib not safe for use in application extensions: /Users/someuser/Library/Developer/Xcode/DerivedData/myapp-dsaagxaaoxqxgxcwdhubkhreboeb/Build/Products/Debug-iphonesimulator/Pods/Alamofire.framework/Alamofire
