找到Xcode项目文件.xcodeproj，查看包内容。
里面有project.pbxproj，用文本编辑器打开。
找到类似如下内容段：
/* Begin XCVersionGroup section */ 6A8CFCCE1D52D4FA00169639 /* CoreDataDemoByFicow.xcdatamodeld */ = { isa = XCVersionGroup; children = ( 6A9B67701DA88B5E004FB82D /* CoreDataDemoByFicow 2.xcdatamodel */, 6A8CFCCF1D52D4FA00169639 /* CoreDataDemoByFicow.xcdatamodel */, ); currentVersion = 6A8CFCCF1D52D4FA00169639 /* CoreDataDemoByFicow.xcdatamodel */; path = CoreDataDemoByFicow.xcdatamodeld; sourceTree = "<group>"; versionGroupType = wrapper.xcdatamodel; }; /* End XCVersionGroup section */
CoreDataDemoByFicow.xcdatamodel
CoreDataDemoByFicow 2.xcdatamodel
要删除还是要排序，现在随便你咯！
请注意备份！
