如何在Tabbar应用中将视图旋转为横向

import UIKit

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        
        let viewToRotate = UIView()
        viewToRotate.frame = CGRect(x: 0, y: 0, width: 100, height: 100)
        viewToRotate.backgroundColor = .red
        
        let rotationTransform = CGAffineTransform(rotationAngle: CGFloat.pi/2)
        viewToRotate.transform = rotationTransform
        
        self.view.addSubview(viewToRotate)
    }
}
