tag(_:)

Declaration

@MainActor @preconcurrency func tag<V>(_ tag: V) -> some MapContent where V : Hashable

Parameters

• tag:

  A Hashable value to use as the map content’s tag.

Return Value

Map content with the specified tag set.

Discussion

Use this modifier to differentiate between selectable content in the map. When the map’s selection binding has the same value as the tag applied to a piece of map content, that content is considered selected.

A ForEach automatically applies a default tag to each enumerated view using the id parameter of the corresponding element. If the element’s id parameter and the the map’s selection input have the same type, you can omit the explicit tag modifier.
