（三）作業說明

雖然說是一個小小的加分作業，但就已經難倒我了

(1)自動播放toggle

let timer = Timer.publish(every: 2, on: .main, in: .common)
    .autoconnect()
Toggle("自動播放", isOn: Binding(
get: {self.autoPlay2}, 
set: {print($0)
      self.autoPlay2 = $0}))
.onReceive(timer) { (value) in
  if self.autoPlay2{
    self.number += 1
    self.number_year = Double(self.number % 10 + 2010)
    var components = DateComponents()
    components.calendar = Calendar.current
    components.year = Int(self.number_year)   
    self.picTime = components.date!
  }
}

(2)data picker & slider連動

上網找了很多方法，還是彼得的教學文章最對味，簡單來說就是透過

custom binding，在date picker 綁定 slider ，slider也綁定 date picker

SwiftUI 的 custom binding
