如何使用UIScrollView显示下一个视图的边缘

import UIKit

class ViewController: UIViewController, UIScrollViewDelegate {
    override func viewDidLoad() {
        super.viewDidLoad()
        
        let scrollView = UIScrollView(frame: CGRect(x: 0, y: 0, width: view.frame.width, height: view.frame.height))
        scrollView.contentSize = CGSize(width: view.frame.width * 2, height: view.frame.height)
        scrollView.isPagingEnabled = true
        scrollView.isScrollEnabled = true
        scrollView.delegate = self
        
        let view1 = UIView(frame: CGRect(x: 0, y: 0, width: view.frame.width, height: view.frame.height))
        view1.backgroundColor = UIColor.red
        scrollView.addSubview(view1)
        
        let view2 = UIView(frame: CGRect(x: view.frame.width, y: 0, width: view.frame.width, height: view.frame.height))
        view2.backgroundColor = UIColor.blue
        scrollView.addSubview(view2)
        
        view.addSubview(scrollView)
    }
    
    // UIScrollViewDelegate方法，监听UIScrollView的滚动事件
    func scrollViewDidScroll(_ scrollView: UIScrollView) {
        // 检查UIScrollView的contentOffset属性，判断是否滚动到边缘
        if scrollView.contentOffset.x == scrollView.contentSize.width - scrollView.frame.width {
            // 滚动到右边边缘
            print("滚动到右边边缘")
        } else if scrollView.contentOffset.x == 0 {
            // 滚动到左边边缘
            print("滚动到左边边缘")
        }
    }
}
