Swift同时检测屏幕左右两侧的触摸

import UIKit

class ViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
        
        let swipeGestureRecognizer = UISwipeGestureRecognizer(target: self, action: #selector(handleSwipe(_:)))
        swipeGestureRecognizer.direction = [.left, .right]
        view.addGestureRecognizer(swipeGestureRecognizer)
    }
    
    @objc func handleSwipe(_ gestureRecognizer: UISwipeGestureRecognizer) {
        if gestureRecognizer.direction == .left {
            // 左侧触摸
            print("左侧触摸")
        } else if gestureRecognizer.direction == .right {
            // 右侧触摸
            print("右侧触摸")
        }
    }
}
