I have added core data to my project and below is the code block of how it's section in pbxproj file looks like. However whenever I make any changes to the project i.e. changing build version or adding a deleting new files to the project, I have noticed "name = "sample-app.xcdatamodeld";" gets deleted automatically from the project file and I have to manually reverse that change. Am I missing any setting for core data or is it a bug somewhere in XCode or Core Data? I am using XCode 15. /* Begin XCVersionGroup section */ 4683EC5B2C10F8B800A5081B /* sample-app.xcdatamodeld */ = { isa = XCVersionGroup; children = ( 4683EC5C2C10F8B800A5081B /* sample-app.xcdatamodel */, ); currentVersion = 4683EC5C2C10F8B800A5081B /* sample-app.xcdatamodel */; name = "sample-app.xcdatamodeld"; path = "sample-app.xcdatamodeld"; sourceTree = "<group>"; versionGroupType = wrapper.xcdatamodel; }; /* End XCVersionGroup section */
