Saving sqlite database with swift

After doing this tutorial

http://www.techotopia.com/index.php/An_Example_SQLite_based_iOS_8_Application_using_Swift_and_FMDB

I found that the database was only created while the app was running. How could I access the database the second time I run the app. And my final goal is to create a database and use the data to display things.

Many thanks in advance!
