Xcode 9 - 无法发出预编译头文件 [英] Xcode 9 - failed to emit precompiled header

问题描述

我通过 MyProjectName-Bridging-Header.h 在 Objective-C 和 swift 中有一个项目，我还配置了 Objective-C 桥接头.我还在 .pch 文件中添加了MyprojectName-Swift.h".

I have a project in Objective-C as well as in swift by taking MyProjectName-Bridging-Header.h and i also configured the Objective-C Bridging Header. Also i have added 'MyprojectName-Swift.h' in .pch file.

这在 xcode 8.2 上运行良好，但是当我从 xcode 9 构建我的项目时，出现以下错误.

This works fine on xcode 8.2 but when i build my project from xcode 9 i am getting the below error.

未能发出预编译头'/Library/Developer/Xcode/DerivedData/MyprojectName-lajanjvhqjnfjksdsndsfkads/Build/Intermediates.noindex/PrecompiledHeaders/MyprojectName-Bridging-Header-swift_44AHJm3Z96qu-clang_2BIMGQVXGEZ09.pch'用于桥接标题'/Documents/MyProjectLocaiton/FoneApp-Bridging-Header.h'

failed to emit precompiled header '/Library/Developer/Xcode/DerivedData/MyprojectName-lajanjvhqjnfjksdsndsfkads/Build/Intermediates.noindex/PrecompiledHeaders/MyprojectName-Bridging-Header-swift_44AHJm3Z96qu-clang_2BIMGQVXGEZ09.pch' for bridging header '/Documents/MyProjectLocaiton/FoneApp-Bridging-Header.h'

请帮我解决这个问题.谢谢！

Please help me out from this. Thanks!

推荐答案

最后我得到了这个问题的解决方案.在我的项目中，Prefix Header 路径没有明确定义.之前的路径是

Finally i got the solution of this issue. In my project the Prefix Header path is not clearly defined. Earlier the path was

$(SRCROOT)/MyPrefixHeaderFile.pch

$(SRCROOT)/MyPrefixHeaderFile.pch

MyPrefixHeaderFile.pch 位于项目文件夹内的另一个文件夹中，因此我将 Prefix Header 路径更新为

MyPrefixHeaderFile.pch is in another folder inside the project folder, So i update the Prefix Header path to

$(SRCROOT)/FolderName/MyPrefixHeaderFile.pch

$(SRCROOT)/FolderName/MyPrefixHeaderFile.pch
