Steps to setting up relational database (sqlite) in swift

I am working on an iOS app and I want to set up a relational database for it. I read that SQLite is a good database to use. I'm making the app in Swift. I've looked at several tutorials but it seems like all the ones that I found have the DBManager class or libraries in objective-c. Therefore, I would need a wrapper for the db class. I'm not really sure how the wrapper works and how I would be calling objective-c methods using swift syntax.

I was wondering if someone could help clarify the whole process for this from creating the database file and adding it to your xcode project to using objective-c libraries with swift syntax in order to run queries against the database file.

Also, is it worth it to just use Core Data which seems easier to use instead?
