SwiftUI -当倒计时结束时，跳转到另一个视图

import SwiftUI

class TimerManager: ObservableObject {
    @Published var timeRemaining = 10
    var timer = Timer()

    func startTimer() {
        timer = Timer.scheduledTimer(withTimeInterval: 1, repeats: true) { timer in
            if self.timeRemaining > 0 {
                self.timeRemaining -= 1
            } else {
                self.timer.invalidate()
                // 倒计时结束，跳转到另一个视图
                // 在这里添加跳转代码
            }
        }
    }
}

import SwiftUI
