Question

我正在将旧的应用程序从swift 3迁移到swift 4，并遇到了以下错误：

error: Multiple commands produce '/Users/.../Library/Developer/Xcode/DerivedData/ ... /Debug-iphonesimulator/CompassV3.swiftmodule/x86_64.swiftmodule':
1) Target 'CompassV3' (project 'Void Navigator'): Ditto /Users/.../Library/Developer/Xcode/DerivedData/.../Debug-iphonesimulator/CompassV3.swiftmodule/x86_64.swiftmodule /Users/.../Library/Developer/Xcode/DerivedData/Void_Navigator-bogrvoiumgmhfwcpvocwtssiwgpm/Build/Intermediates.noindex/Void Navigator.build/Debug-iphonesimulator/CompassV3.build/Objects-normal/x86_64/CompassV3.swiftmodule
2) Target 'Outdoor Navigator' (project 'Void Navigator'): Ditto /Users/.../Library/Developer/Xcode/DerivedData/.../Debug-iphonesimulator/CompassV3.swiftmodule/x86_64.swiftmodule /Users/.../Library/Developer/Xcode/DerivedData/Void_Navigator-bogrvoiumgmhfwcpvocwtssiwgpm/Build/Intermediates.noindex/Void Navigator.build/Debug-iphonesimulator/Outdoor Navigator.build/Objects-normal/x86_64/CompassV3.swiftmodule

CompassV3构建应用程序

Outdoor navigator是扩展名。

看起来像是冲突，但我不知道如何解决。

项目仍处于快速版本3。

Answer 1

您很可能有两个目标使用相同的产品名称。

您能否同时在项目中定位目标，请转到“构建设置”并在“包装”部分中检查“产品模块名称”的值？

错误：多个命令产生... x86_64.swiftmodule
