如何在ViewControllers之间改变segue的速度

import UIKit

class CustomSegue: UIStoryboardSegue {
    override func perform() {
        let sourceViewController = self.source
        let destinationViewController = self.destination
        sourceViewController.present(destinationViewController, animated: true, completion: nil)
        
        // 设置动画速度
        let transitionCoordinator = destinationViewController.transitionCoordinator
        transitionCoordinator?.animate(alongsideTransition: { _ in
            // 在这里设置动画速度
        }, completion: nil)
    }
}

class ViewController: UIViewController {
    override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
        if let customSegue = segue as? CustomSegue {
            // 设置动画速度
            customSegue.animationDuration = 0.5
        }
    }
}

import UIKit

class CustomTransition: NSObject, UIViewControllerAnimatedTransitioning {
    func transitionDuration(using transitionContext: UIViewControllerContextTransitioning?) -> TimeInterval {
        return 0.5 // 设置动画速度
    }
    
    func animateTransition(using transitionContext: UIViewControllerContextTransitioning) {
        // 在这里实现动画
    }
}

class ViewController: UIViewController {
    override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
        let destinationViewController = segue.destination
        destinationViewController.transitioningDelegate = self
    }
}

extension ViewController: UIViewControllerTransitioningDelegate {
    func animationController(forPresented presented: UIViewController, presenting: UIViewController, source: UIViewController) -> UIViewControllerAnimatedTransitioning? {
        return CustomTransition()
    }
    
    func animationController(forDismissed dismissed: UIViewController) -> UIViewControllerAnimatedTransitioning? {
        return CustomTransition()
    }
}
