回答1:
Even worse, though I'd remove that project, crash had occurred repeatedly in my case. I fixed this problem by editing project.pbxproj(in .xcodeproject file) manually.
回答2:
Apparently this is due to the new version of XCodeProjects. I found a work around by pre-compiling the library that was causing the issue and then using the linker to link to the .a file. I also had to copy the .a library into the DerivedData path.
The real solution was to remove the project and replace it with an updated project for the new version of XCode.
回答3:
I fixed it by going back to a backup of the project.pbxproj. After that I removed the library that was causing the issue (reference only). Added the library to the project again and deleted the DerivedData.
