Database Integration/Overlap problem between swift and objective C app

Dear team,
Hope you're all doing well. I'm stuck with this problem where my new swift project data model name and structure are overriding my Objective - C project core data model and structure. I need to keep the same model and database on swift as it was in Objective-C. Please let me know if you've encountered this problem. 6:42 and your help is really appreciated.
