🔸view size

SwiftUI ⟩ view ⟩ layout ⟩ size

SwiftUI has built-in views that manage size in different ways:

• Expanding to fill the available space (offered by their parent): (Color, LinearGradient, Circle ...)

• Resizing to fit their content: (have an ideal size that varies according to their contents) (Text, container views ...)

• Maintaining a specific size that doesn't change: (have an ideal size that never varies) (Toggle, DatePicker...)

📘 手冊

• Limit the view size

• frame(width:height:alignment:)
