For me, the best results came from combining Zeesha's answer and sazz's answer.

Add the following lines to AppDelegate.swift:

var orientationLock = UIInterfaceOrientationMask.portrait
var myOrientation: UIInterfaceOrientationMask = .portrait
func application(_ application: UIApplication, supportedInterfaceOrientationsFor window: UIWindow?) -> UIInterfaceOrientationMask {
    return myOrientation
}  

Add the following line to your view controller class:

let appDel = UIApplication.shared.delegate as! AppDelegate

Add the following lines to your view controller's viewDidLoad():

appDel.myOrientation = .landscape
UIDevice.current.setValue(UIInterfaceOrientation.landscapeLeft.rawValue, forKey: "orientation")

(optional) Add this line to your dismiss function:

appDel.myOrientation = .portrait
UIDevice.current.setValue(UIInterfaceOrientation.portrait.rawValue, forKey: "orientation")

What these lines of code do is set the default orientation to portrait, rotate it landscape when the view controller loads, and then finally reset it back to portrait once the view controller closes.
