iOS program doesn't found SQLite database

I change my program code to latest version 2020r2.1. But now it doesn’t found the database. It works fine before. Opening code is same as EddiesElecronics which hasn’t any problem.
DB type is SQLiteDatabase and it is in App properties, App is MobleApplication and CopyDB is path to the database. The database is in the same folder as my project.

Check your copyFilesStep to make sure the original file is still there and is being copied to Resources.
