How to know the current orientation of a iDevice - ios

Question

I'm doing an app for Mathematics lessons & exercices...
I have only coded the MainMenu, but I've got a problem.
Indeed, I would like to know the current orientation to set up my stuff.
However, I tried different ways to know the current orientation, but I didn't succeed :
if UIDevice.current.orientation == UIDeviceOrientation.portrait {
NSLog("Portrait")
}
else if UIDevice.current.orientation == UIDeviceOrientation.landscapeRight || UIDevice.current.orientation == UIDeviceOrientation.landscapeRight {
NSLog ("Landscape")
}
I also see this answer, but it's not working (or maybe I haven't understood well) : Getting device orientation in Swift , bu
I would like to specify that I'm in UIViewController in the ViewDidLoad().
Thanks for your help 👨‍💻

I set up a little prototype app with a button which checks for device orientation changes when pressed. Here is a link to the documentation which hopefully helps further your project along.
class ViewController: UIViewController {
let device = UIDevice.current
override func viewDidLoad() {
super.viewDidLoad()
device.beginGeneratingDeviceOrientationNotifications()
}
#IBAction func orientation(_ sender: UIButton) {
if device.isGeneratingDeviceOrientationNotifications {
switch device.orientation {
case .landscapeLeft:
print("Landscape Left")
case .portrait:
print("Portrait")
case .landscapeRight:
print("Right")
case .portraitUpsideDown:
print("Upside down")
case .unknown:
print("Unknown")
default:
print("Else")
}
}
}
}
