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！
