Use coordinator.animate to determine when the animation is over.
class ViewController: UIViewController {
public override func viewWillTransition(to size: CGSize, with coordinator: UIViewControllerTransitionCoordinator) {
super.viewWillTransition(to: size, with: coordinator)
coordinator.animate(alongsideTransition: { (context) in
guard let windowInterfaceOrientation = self.windowInterfaceOrientation else { return }
if windowInterfaceOrientation.isLandscape {
// activate landscape changes
} else {
// activate portrait changes
}
})
}
private var windowInterfaceOrientation: UIInterfaceOrientation? {
return UIApplication.shared.windows.first?.windowScene?.interfaceOrientation
}
}
