Swift编译错误

Question

我的团队和我在Xcode 9.4中编译Objective C项目时遇到了问题。任何人都知道发生了什么？

<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import { StyleSheet, Text, View, Image} from 'react-native'; 并删除该列表中的重复条目，参考编译错误中列出的文件。看起来列出了一些文件用于编译两次会导致此问题。

这通常是xcode项目文件中的一个问题，由于手动解决了项目文件中的git冲突，我遇到了这个问题。

如果这不能解决您的问题，请确保您没有项目中具有相同名称的文件。
