The gist of the article is that we can omit the verbose #selector syntax by adding a convenience property:

#!swift
private extension Selector {
    static let buttonTapped = 
        #selector(ViewController.buttonTapped(_:))
}
...
button.addTarget(self, action: .buttonTapped, 
    forControlEvents: .TouchUpInside)

I’d make that not private but internal and group these in a struct to separate them from other Selector stuff:

#!swift
extension Selector {
    // One for each view module ...
    struct Banana {
        static let changeSizeTapped = 
            #selector(BananaViewController.changeSizeTapped(_:))
    }

    struct Potato {
        static let peelSelected = 
            #selector(PotatoViewController.peelSelected(_:))
    }
}

// ...

button.addTarget(self, action: .Potato.peelSelected, 
    forControlEvents: .TouchUpInside)

Great tip!
