与RestKit和CocoaPods的Xcode 7链接器错误

Question

我刚刚升级到Xcode 7和CocoaPods 0.38.2,在解决了一些Swift 2问题后,我的混合Objective-C&Swift项目针对iOS 7得到了以下链接器错误:

Undefined symbols for architecture x86_64:
  "_OBJC_CLASS_$_RKManagedObjectRequestOperation", referenced from:
      objc-class-ref in NetworkHelper.o
  "_OBJC_CLASS_$_RKManagedObjectResponseMapperOperation", referenced from:
      type metadata accessor for ObjectiveC.RKManagedObjectResponseMapperOperation in MappingHelper.o
  "_RKLogCoreDataError", referenced from:
      ___33-[RKEntityByAttributeCache load:]_block_invoke in libRestKit.a(RKEntityByAttributeCache.o)
      ___43-[RKManagedObjectImporter finishImporting:]_block_invoke in libRestKit.a(RKManagedObjectImporter.o)
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

CoreData包含在我的.pch文件中,并且在桥接头中包含在RestKit之前,并且Bitcode已关闭.我正在使用RestKit 0.24.1.

由于似乎RestKit没有检测到CoreData框架的存在,并且其条件声明因此被传递,我已经尝试了很多方法来告诉我的应用程序或RestKit pod有关Core Data的存在,但没有似乎有所帮助.

升级你的cocoapods和xcode7.0.1

并删除 xcworkspace 并再次安装 pod。
