SQLite database file is just a normal file, you do not need any special steps to update it.

Get the file path or URL to the SQLite file , and use NSFileManager 's method removeItemAtPath:error: or removeItemAtURL:error:

Then create the new database the same way you created the old one.

Also check this link if get any problem.

EDIT : You can delete your old SQlite database file if it's copied in document directory. You CAN NOT delete files from bundle.
