How to lock orientation of one view controller to landscape mode [iOS13] - uiviewcontroller

Question

I have this solution: How to lock orientation of one view controller to portrait mode only in Swift
It was working fine but now on iOS 13 it didn't work anymore.
I try this solution: Screen rotation glitch on iPadOS 13
But it doesn't fix it.
Can someone have a working solution for iPhone app in portrait but only one UIViewController in landscape?
Edit:
I made a sample app, it is working fine with iOS 12.4.2 and iPhone 6.
But my problem it isn't working with iOS 13.1.3 and iPhone X.

Edit 2:
Thanks to #donnywals, I success to keep my orientation as on iOS 12.
I just need some help to clean the main screen during transition. The "TOP" label is 90px from top of superview. As you can see, the current portrait page is resized during the transition.
Anyone know how to avoid it?

Answer 1

You can lock a view controller's orientation by overriding its supportedInterfaceOrientations property:
class ViewController: UIViewController {
override var supportedInterfaceOrientations: UIInterfaceOrientationMask {
return .landscape
}
// rest of your code
}
Edit:
Based on the sample project, you need to opt-out of the new presentation style to get the same behavior you had on iOS 13. Either set modalPresentationStyle = .fullScreen on the view controller that you're presenting in code or select the corresponding option in Interface Builder.

This is a tested code and I have implemented the same and its working for me - Forcing a controller to landscape mode
In the method viewWillAppear add the following:
NSNumber *value=[NSNumber numberWithInt: UIDeviceOrientationLandscapeLeft];
[[UIDevice currentDevice] setValue:value forKey:#"orientation"];
Add the following methods to the view controller
- (UIInterfaceOrientationMask)supportedInterfaceOrientations {
return UIInterfaceOrientationMaskLandscape;}
- (UIInterfaceOrientation) preferredInterfaceOrientationForPresentation{
return (UIInterfaceOrientationLandscapeLeft | UIInterfaceOrientationLandscapeRight);}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation{
return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown);}
- (BOOL)shouldAutorotate {
return true;}
