Xcode 9 - failed to emit precompiled header

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.

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

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'

Please help me out from this. Thanks!

Solution

  • 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

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

    $(SRCROOT)/FolderName/MyPrefixHeaderFile.pch
