When I run the code below, a lot of strange errors are output to the console. If you read them, you will notice that they are all referred to some "database". (What nonsense!) I'm guessing it has something to do with the SQLite module. Most likely, the "Context" variable makeUIViewController(context: Self.Context) by the same name is also present in SQLite. If the same code is placed in a new clean project, without dependencies, it will work without errors. Can I specify Context in some other way or restrict the scope of the SQLite module? Or maybe the error is in something else?
The library I use: https://github.com/stephencelis/SQLite.swift
