How to use SQLite database in Swift 4.2?

Question

SQLite

Good day!
When developing an application in Swift4.2, I encountered the need to use an existing database written in SQLite.
The application is an ordinary line in one of which you enter a value, and in the rest there are data taken from the database.
I was looking for various solutions in order to link, but alas.
1. Using FMDB: due to poor knowledge of the SWIFT language, I could not translate the code from Habr to the version I needed.
2. Using SQLite.swift: the same, something went wrong while writing code and trying to use existing codes.
3. Using CoreData: I haven’t considered it yet, but there is a main question here: can one SQLite table be used in CoreData (so that I don’t have to interrupt all the values)?
Please help me figure it out...
Is there an up-to-date instruction / manual somewhere on how to use the SQLite database in Swift 4.2 (not for Swift 3)?

Answer 1

To be honest, if with such an abundance of different materials, you can’t migrate and use the database, then it’s probably better to learn Swift.
In descending order of complexity:
GRDB
SQLite Swift
Core Data

Answer 2

And at the same time take into service the database from realm.io
