Lock screen Orientation to portrait - ios swift

Question

I am creating an application with support only for portrait mode. I don't want Landscape or Portrait upside down. I tried some code. Which allows me to lock in portrait mode.

I am using navigationcontroller and presentviewcontroller. Now my problem is: 1. If I rotate my device upside down and open my application it opens in upside down mode which is wrong. 2. I click some button and enter to presentviewcontroller it returns to portrait mode.

I want all the navigationcontroller and presentviewcontroller in portrait mode

My codes:

I set device orientarion portrait in Target -> General -> Deployment Info -> Portrait

In my appdelagate.swift:

func application(application: UIApplication, supportedInterfaceOrientationsForWindow window: UIWindow?) -> UIInterfaceOrientationMask {
        return UIInterfaceOrientationMask.Portrait
    }

In my First view controller. Which is basically child of Navigation Controller

override func shouldAutorotate() -> Bool {


            return false
        }

        override func supportedInterfaceOrientations() -> UIInterfaceOrientationMask {
            return [UIInterfaceOrientationMask.Portrait ]
        }

Edit 1:

Also I set StoryBoard -> ViewController -> Attribute Inspector -> Orientation -> Portrait

Edit 2:

My settings file

Answer 1

Go To Target --> General and set Orientation Mode to Portrait.

Also check info.plist. Make sure Supported Interface Orientations contains only one value(Portrait). Sometime it removes from settings but not updated in plist file.
