Swift extensions: NSStoryboard

NSStoryboard.md

I enjoy making and playing with little DSL-ish extensions for Cocoa types in Swift. For instance, the code below allows me to write cool

storyboard.VC["foo_bar"]
storyboard.VC.initial

instead of:

storyboard.instantiateControllerWithIdentifier("foo_bar") as NSViewController
storyboard.instantiateInitialController() as NSViewController

Of course I could've just as well extended NSStoryboard with a method like .getVC(), but this is all just for fun anyway ;)

Previously in Swift Extensions:

• NSTimer

NSStoryboard.swift

import Cocoa

class NSStoryboardVCGetterProxy {
    private weak var storyboard: NSStoryboard!
    private init(storyboard: NSStoryboard) {
        self.storyboard = storyboard
    }
    
    subscript(identifier: String) -> NSViewController {
        return storyboard.instantiateControllerWithIdentifier(identifier) as NSViewController
    }
    
    var initial: NSViewController {
        return storyboard.instantiateInitialController() as NSViewController
    }
}

extension NSStoryboard {
    var VC: NSStoryboardVCGetterProxy {
        return NSStoryboardVCGetterProxy(storyboard: self)
    }
}
