SwiftUI ⟩ view ⟩ groupings ⟩ ForEach
ForEach generates views for each element in a collection.
ForEach requires that each element provide an id,
either explicitly in the
ForEachinitializer,or by conforming to the Identifiable protocol.
// <collection> must conform to Identifiable
ForEach(collection) { element in
Text(element.name)
}⭐️ 注意:
ForEach doesn’t get hit by the 10-view limit. ⭐️
ForEach 不一定是 View,也可能是其他東西,如:TableRowContent
(👉 See: 📜 協定)
