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 ForEach initializer,

  • 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
