SwiftLint Vertical Whitespace in between functions

I like to have a single empty line in between logical blocks, and two empty lines in between functions, at the top of a class, and at the bottom of a class (between the last function and the class's closing bracket).

In order not to get the warning about having too much vertical whitespace, I had to customize to the rule to allow up to two lines, but that is of course not specific to inside and outside of functions, so SL won't catch such inconsistencies.

It would be nice to be able to customize this.

Example:

// MARK: Life Cycle

    override func viewDidLoad() {
        super.viewDidLoad()

        let myButton = Button

        let myTable = Table
    }


    override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(animated)

        let myButton = Button

        let myTable = Table
    }

That's absolutely something I'd be in favor of allowing configuring. Is this something you'd be interested in contributing yourself or are you asking for someone else to build this? I'm happy to point you in the right direction if you're unsure where to start.

I’m very interested in helping out and unsure where to start just as much 😄

Here's roughly the steps you'd take to build this:

Add a configuration option for how many lines of whitespace should be between functions in VerticalWhitespaceConfiguration.swift. This is the file where configuration options for the vertical_whitespace rule are defined.
In VerticalWhitespaceRule.swift, add a check for your new configuration option and validate that there's the right amount of spacing for the code style you want to enforce.
Add tests to VerticalWhitespaceRuleTests.swift following how the other tests in that file are set up.

Lack of this feature is the main reason I haven't been using SwiftLint. Perhaps I'll take a try at adding this.
