Swift: Enable landscape for one controller and for the rest only portrait

Question

My application was only in portrait mode, but I need a controller to also support landscape.

Here my info.plist:

    <key>UISupportedInterfaceOrientations</key>
    <array>
        <string>UIInterfaceOrientationPortrait</string>
        <string>UIInterfaceOrientationPortraitUpsideDown</string>
        <string>UIInterfaceOrientationLandscapeLeft</string>
        <string>UIInterfaceOrientationLandscapeRight</string>
    </array>

And in my app delegate I have added this:

var shouldRotate = false

    func application(_ application: UIApplication, supportedInterfaceOrientationsFor window: UIWindow?) -> UIInterfaceOrientationMask {
        return shouldRotate ? .allButUpsideDown : .portrait
    }

In my controller:

    override func viewDidLoad() {
        super.viewDidLoad()
        let appDelegate = UIApplication.shared.delegate as! AppDelegate
        appDelegate.shouldRotate = true // or false to disable rotation
    }

But the controller not rotate, what is my mistake? This controller is open in modal on a navigation controller

Past in controlllers seprately, According to your requirment.

override public var shouldAutorotate: Bool {
    return true
} 

override public var supportedInterfaceOrientations: UIInterfaceOrientationMask {
    return .all
}

override public var preferredInterfaceOrientationForPresentation: UIInterfaceOrientation {
    return .all
}

this should be in viewcontroller, where you want both landscape and portrait.

// other Viewcontrollers :

override public var shouldAutorotate: Bool { return false }

override public var supportedInterfaceOrientations: UIInterfaceOrientationMask {
    return .portrait
}

override public var preferredInterfaceOrientationForPresentation: UIInterfaceOrientation {
    return .portrait
}

// add this in viewcontroller ehere you want Application in portrait oreintation.

Enable all required orientation for whole Application.

And please remove your code in appDelegate related to orientation

This is not what I want, this code forces the landscape. I want the controller support portrait AND landscape mode. — Mickael Belhassen, Jul 07 '20 at 07:14
