callAsFunction(id:value:)

Opens a window defined by the window group that presents the specified value type and that’s associated with the specified identifier.

Declaration

@MainActor @preconcurrency func callAsFunction<D>(id: String, value: D) where D : Decodable, D : Encodable, D : Hashable

Parameters

  • id:

    The identifier of the scene to present.

  • value:

    The value to present.

Discussion

Don’t call this method directly. SwiftUI calls it when you call the openWindow action with an identifier and a value:

openWindow(id: "message", value: message.id)
