今天要介紹SwiftUI當中Layout View的部份的VStack、HStack與Spacer

VStack

A view that arranges its children in a vertical line.
宣告一個區域，讓其中的子物件依照垂直排列

參數：

• spacing：VStack裡各物件的間距
• alignment：VStack裡各物件靠哪邊排列(預設是.center)
  

HStack

A view that arranges its children in a horizontal line.
和VStack一樣是宣告區域，只是改為讓子物件水平排列

參數：

• spacing：HStack裡各物件的間距
• alignment：HStack裡各物件靠哪邊排列(預設是.center)
  

Spacer

A flexible space that expands along the major axis of its containing stack layout, or on both axes if not contained in a stack.
可以用spacer將元件隔開做出想要的排列方式
