SwiftUI ⟩ view ⟩ layout

SwiftUI layout system:

1. Parent proposes a size for child.

2. Child chooses its own size.

3. Parent places child in parent’s coordinate space.

⭐️ 重點

SwiftUI views manage size in different ways:

• "push-out" views: expand to fill space offered by parent. 👉Color, LinearGradient, Circle...

• "pull-in" views: have ideal size that varies according to their contents. 👉 Text , container views (HStack, VStack , ...)

• "fixed" views: have ideal size that never varies. 👉 Toggle or DatePicker...
