iPad orientation programmatically not working - swift

Question

I have an issue about the orientation on iPad.
I disabled the orientation on iPhone but i can change it programmatically on some specific controller.
But on iPad i can’t. i don’t know why although i searched in this website and some developers write answers to check UIRequiresFullScreene and i do it.
But it disables the orientation on all screens.
Is there any way to give ability to change orientation on specific controller on iPad ?
The following code i used to change iPad Orientation but it is not working.
UIDevice.current.setValue(UIInterfaceOrientation.landscapeLeft.rawValue, forKey: "orientation")
Thanks advance

When you set programmatically the orientation of the device. To perform the orientation animation the function
func application(_ application: UIApplication, supportedInterfaceOrientationsFor window: UIWindow?) -> UIInterfaceOrientationMask
from AppDelegate is being called.
If you have set it there to return only UIInterfaceOrientationMask.portrait you will never see the transition.
Also I personally have these kind of problems and to solve this I had to programmaticaly force the phone to rotate to the current Orientation and then to rotate to the wanted orientation.
Example for phone to rotate landscapeLeft from portrait
func setOrientationToLandScapeOnly() {
appDelegate.shouldForceLandscapeOnly = true
appDelegate.shouldForcePortraitOnly = false
if UIDevice.current.userInterfaceIdiom == .phone {
switch UIApplication.shared.statusBarOrientation {
case .landscapeLeft, .landscapeRight:
return
default:
APIOrientationHandler.shared.setDeviceValueForOrientation(UIInterfaceOrientation.portrait.rawValue)
APIOrientationHandler.shared.setDeviceValueForOrientation(UIInterfaceOrientation.landscapeLeft.rawValue)
return
}
}
}
And inside AppDelegate.swift
func application(_ application: UIApplication, supportedInterfaceOrientationsFor window: UIWindow?) -> UIInterfaceOrientationMask {
if shouldForcePortraitOnly {
return UIInterfaceOrientationMask.portrait
}
if shouldForceLandscapeOnly {
return UIInterfaceOrientationMask.landscape
}
if (UIDevice.current.userInterfaceIdiom == UIUserInterfaceIdiom.pad) {
return UIInterfaceOrientationMask.landscape
}
return UIInterfaceOrientationMask.portrait
}
