Insert, delete sqlite not working on device?

Question

SQLite

Hello, I'm asking for help.
On the simulator insert, delete queries work, on the phone they don't.
I connect to the database like this:

let path = Bundle.main.path(forResource: "base.sqlite", ofType: nil)!
        let baseFile = URL(fileURLWithPath: path)
        var db: OpaquePointer?
        if sqlite3_open(baseFile.path, &db) != SQLITE_OK {
            print("error opening database")
        }

The database was added in this way https://stackoverflow.com/questions/46231153/how-t...
It seems that the ability to change the database file is blocked on the device (phone), it reads normally from the database (select).
Tell me, please, what could be the problem.
