Unable to force UIViewController orientation

Question

I have a portrait application with one landscape ViewController.

I\'ve been digging a lot on how to force the orientation to landscape when the app is locked to port

As an update to Reinier Melian's post, here is the UINavigationController extension in Swift 3:

import UIKit

extension UINavigationController {
    override open var shouldAutorotate: Bool {
        return (self.viewControllers.last?.shouldAutorotate)!
    }

    override open var supportedInterfaceOrientations: UIInterfaceOrientationMask {
        return (self.viewControllers.last?.supportedInterfaceOrientations)!
    }

    override open var preferredInterfaceOrientationForPresentation: UIInterfaceOrientation {
        return (self.viewControllers.last?.preferredInterfaceOrientationForPresentation)!
    }
}

Unfortunately, this code crashes if you call a UIImagePickerController, as that is contained within a UINavigationController whose last view controller is nil.
