Easily access master and detail view controllers on UISplitViewController

UISplitViewController+Soffes.swift

import UIKit

extension UISplitViewController {
	convenience init(masterViewController: UIViewController, detailViewController: UIViewController) {
		self.init()
		viewControllers = [masterViewController, detailViewController]
	}

	var masterViewController: UIViewController? {
		return viewControllers.first
	}

	var detailViewController: UIViewController? {
		guard viewControllers.count == 2 else { return nil }
		return viewControllers.last
	}
}

UISplitViewController has a private var detailViewController that this will interfere with!

Hah I wonder when that was added. Maybe just rename them to master and detail :)
