下からシートを出すコードでUIWindowScene.windows使う

        let actionSheet = UIAlertController(title: "選択", message: nil, preferredStyle: .actionSheet)
        actionSheet.addAction(UIAlertAction(title: "1つめ", style: .default) { _ in
            // なんとかかんとか
        })
        actionSheet.addAction(UIAlertAction(title: "2つめ", style: .default) { _ in
            // なんとかかんとか
        })
        actionSheet.addAction(UIAlertAction(title: "キャンセル", style: .cancel))

        UIApplication.shared.windows.first?.rootViewController?.present(actionSheet, animated: true)

というコード書いたら

'windows' was deprecated in iOS 15.0: Use UIWindowScene.windows on a relevant window scene instead

で非推奨の警告が・・

以下に置き換えた

        if let windowScene = UIApplication.shared.connectedScenes.first as? UIWindowScene,
           let window = windowScene.windows.first,
           let rootViewController = window.rootViewController {
            rootViewController.present(actionSheet, animated: true, completion: nil)
        }
