SQLCipher Working But Incorrect Password

I've just implemented SQLCipher in my app to encrypt one fairly simple database. I followed all of the setup instructions carefully on this tutorial and the project is building and the app is running successfully. However, when I use their sample code to encrypt my database, my password is somehow incorrect and I am now unable to open my database. Here is the code:

NSString *path = [[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0] 

                      stringByAppendingPathComponent: @"dict.sqlite"];

if (sqlite3_open([path UTF8String], &database) == SQLITE_OK) {

        const char* key = [@"BIGSecret" UTF8String];

        sqlite3_key(database, key, strlen(key));

        if (sqlite3_exec(database, (const char*) "SELECT count(*) FROM sqlite_master;", NULL, NULL, NULL) == SQLITE_OK) {

            // password is correct, or, database has been initialized

            NSLog(@"Correct Password :)");

        } 

        else {

            // incorrect password!

            NSLog(@"Incorrect Password :(");

        }

    }

    else {

        sqlite3_close(database);

        NSAssert1(NO, @"Failed to open database with message '%s'.", sqlite3_errmsg(database));

    }

}

sqlite3 *database; is declared in my interface. My app is crashing on this line:

if (sqlite3_prepare_v2(database, sql, -1, &init_statement, NULL) != SQLITE_OK) {

    NSAssert1(NO, @"Error: failed to prepare statement with message '%s'.", sqlite3_errmsg(database));

}

Everything worked just fine without the encryption, so there is no issue with the rest of my code. The console prints "Incorrect Password :(" before the crash. The crash log is: Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Error: failed to prepare statement with message 'file is encrypted or is not a database'.' There is clearly an issue with the password. Any help?

Thanks.
