如何使用UIPanGestureRecognizer实现180度角的3D旋转和3D平移CALayer？

import UIKit

class ViewController: UIViewController {

    var layer: CALayer!
    var initialAngle: CGFloat = 0.0
    var initialPosition: CGPoint = .zero

    override func viewDidLoad() {
        super.viewDidLoad()

        // 创建一个CALayer
        layer = CALayer()
        layer.bounds = CGRect(x: 0, y: 0, width: 100, height: 100)
        layer.position = view.center
        layer.backgroundColor = UIColor.red.cgColor
        view.layer.addSublayer(layer)

        // 创建UIPanGestureRecognizer对象
        let panGesture = UIPanGestureRecognizer(target: self, action: #selector(handlePanGesture(_:)))
        view.addGestureRecognizer(panGesture)
    }

    @objc func handlePanGesture(_ gesture: UIPanGestureRecognizer) {
        let translation = gesture.translation(in: view)
        let velocity = gesture.velocity(in: view)

        switch gesture.state {
        case .began:
            // 记录初始角度和位置
            initialAngle = atan2(layer.transform.m12, layer.transform.m11)
            initialPosition = layer.position

        case .changed:
            // 计算旋转角度和平移距离
            let angle = initialAngle + translation.x / view.bounds.width * .pi
            let distance = translation.y

            // 创建旋转和平移的变换矩阵
            var transform = CATransform3DIdentity
            transform.m11 = cos(angle)
            transform.m12 = -sin(angle)
            transform.m34 = -1.0 / 500.0
            transform = CATransform3DTranslate(transform, 0, 0, distance)

            // 应用变换
            layer.transform = transform

        case .ended, .cancelled:
            // 复位初始角度和位置
            initialAngle = 0.0
            initialPosition = .zero

        default:
            break
        }
    }
}
