When I build project, I see build error: ProjectName.debug.xcconfig unable to open file. I couldn't understand my problem for a long time, but today I take attention, what directory is wrong: full error: projectName/Pods/Pods...ProjectName.debug.xcconfig unable to open file Where Pods part duplicated, so correct directory must be as projectName/Pods...ProjectName.debug.xcconfig How to fix it?
In Xcode 10.1, after trying other suggestions found here #8091 (comment) and at Incorrect path for Pods.debug.xcconfig in Xcode? I found that Kaspik's suggestion worked:
pod deintegrate
pod install
Edit the .xcodeproj/project.pbxproj file and change the PBXGroup path = Pods to name = Pods.
