Swift编译错误[重复]

Question

我和我的团队在 Xcode 9.4 中编译 Objective C 项目时遇到问题。有人知道发生了什么吗？

<unknown>:0: error: filename "Message+CoreDataClass.swift" used twice: '/Users/josepmmirabent/houtel-ios-2016/Houtel2/DerivedData/Jumbotours/Build/Intermediates.noindex/Jumbotours.build/Debug-iphonesimulator/Jumbotours.build/DerivedSources/CoreDataGenerated/Model/Message+CoreDataClass.swift' and '/Users/josepmmirabent/houtel-ios-2016/Houtel2/DerivedData/Jumbotours/Build/Intermediates.noindex/Jumbotours.build/Debug-iphonesimulator/Jumbotours.build/DerivedSources/CoreDataGenerated/Model/Message+CoreDataClass.swift'

谢谢！

进入您的project settings > select your main app target > Build phases > Compile Sources 并删除该列表中引用编译错误中列出的文件的重复条目。看起来有些文件被列出了两次编译，这会导致这个问题。

这通常是 xcode 项目文件中的问题，由于手动解决项目文件中的 git 冲突而发生此问题。

如果这不能解决您的问题，请确保项目中没有同名文件。
