Updates for Xcode 12

[devandanger]

I was playing with some function builder use cases and I really liked the idea of this package.
If you're interested I gave it a bit of TLC.

Corrected what I think might have been is a breaking language construct between Xcode 12 and 11 (or whatever those swift versions are exactly.

I also just made the access modifiers more consistent.

I do not know if this works correctly in Xcode 11.x, but I'm not sure if that's a guarantee regardless based on where function builders are currently in the language design.

@q231950 - Thoughts on this?

Hi @devandanger, thanks & I'll have a look later today : )

First of all, sorry for noticing this late, I only got a notification on my phone with the @-mention 😬

This is fantastic @devandanger, thank you so much! And it's great that you had a look at the library. I used it a bit in a private project and I noticed that sometimes it was a bit tedious (and one might also question the subclassing of Step<Context>) to
create steps. In that project I created a GeneralStep where you can do anything with a title so that it appears in the test result view of Xcode:

Given {
    GeneralStep("I log in") {
        // some function that is defined in my test case
        self.login(name: "John Doe", login: "123456789", password: "***", library: "The New York Public Library")
    }
}

Implementation was quite straightforward to make this possible:

class GeneralStep: Step<Context> {
        let content: (() -> ())?
        let contentWithContext: ((_ context: inout Context) -> ())?
        let _title: String

        convenience init(_ title: String, contentWithContext: ((_ context: inout Context)->())? = nil) {
            self.init(title, contentWithContext: contentWithContext, content: nil)
        }

        convenience init(_ title: String, content: (()->())? = nil) {
            self.init(title, contentWithContext: nil, content: content)
        }

        init(_ title: String, contentWithContext: ((_ context: inout Context)->())?, content: (()->())?) {
            self.content = content
            self.contentWithContext = contentWithContext
            self._title = title
        }

        override var title: String {
            _title
        }

        override func execute(in context: inout Context) {
            content?()
            contentWithContext?(&context)
        }
    }

I think I will add this to the package soon, in case you're interested.
