Actually I am little confuse with your code. Are you trying to programmatically create a database in the app bundle and then copying it to documents directory? If this is what you are doing then you need to know that you can’t create or modify anything in app bundle. You must create this database in Documents directory. You should do something like this –

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory , NSUserDomainMask, YES);
    NSString *documentsDir = [paths objectAtIndex:0];

    NSString * databasePath = [documentsDir stringByAppendingPathComponent:@"XYZ.sqlite"];

    // generate databasePath programmatically
    if(sqlite3_open([databasePath UTF8String], &database) == SQLITE_OK) 
    {

        // your  code here
    }

But if you already have a database in your app (and not dynamically creating) and you just want to copy it to documents directory then you should follow @Santosh Gurram answer.
