如何使用旋转动画在横向模式下呈现ViewController？

override var supportedInterfaceOrientations: UIInterfaceOrientationMask {
    return .landscape
}

let landscapeViewController = LandscapeViewController()
self.addChild(landscapeViewController)
self.view.addSubview(landscapeViewController.view)
landscapeViewController.didMove(toParent: self)

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)
    
    UIView.animate(withDuration: 0.3) {
        self.view.transform = CGAffineTransform(rotationAngle: .pi / 2)
    }
}

override func viewWillDisappear(_ animated: Bool) {
    super.viewWillDisappear(animated)
    
    UIView.animate(withDuration: 0.3) {
        self.view.transform = .identity
    }
    
    self.willMove(toParent: nil)
    self.view.removeFromSuperview()
    self.removeFromParent()
}
