Remove linting

[OlofT]

Linting has no place in a library since its users will never edit the code. Linting is something a company does internally.
It also prevents the library to be used by others. You can test this by setting up a new user, creating a new project and just adding the library - basic compile will not work.

Hello Olof!
It's in our plans to remove the swiftlint plugin but it was left for later and eventually forgotten. We will work on it and get the changes in in the next days.
Thanks!
