東西越來越多 做點紀錄好了
學到 class 如何像 struct 一樣變更 使用@ ObseredObject 代替 @ State
使用sheet，sheet像 alert 一樣使用一個bool當作開關，把另一個view開起來，
使用@ Environment(\.presentationMode)得到現在這個veiw是否正在顯示，可以用它來把自己關閉，明天繼續 36

使用onDelete 把ForEach裡的物件刪除，也可以在NavigationView加上EditButton，也可以使列表裡的東西刪除
UserDefault可以儲存少量的資料，像Unity的PlayerPrefs一樣，儲存取出時都需要一個Key來做存取
Codable讓struct資料封裝成Json, xml等，用以傳輸或著用UserDefault存起來

100 Days of SwiftUI – Day 37 – Hacking with Swift
複習使用class 使用 ObservableObject protocol，property使用@ Published
使用@ ObservedObject 宣告 ObservableObject物件 使得View裡面變更的Published的property 會跟著變更
認識ForEach裡面使用的id:\.xxx，代表xxx是唯一的可辨別的，而如果struct符合Identifiable protocol ，就可以免去使用id:\.xxx因為他已經是可以辨識每個成員的狀態，符合Identifiable protocol 必須要實作id property，id可以使用UUID()來製作，明天繼續37
