Parameters パラメータ

label

Localized string used to show this Rotor entry to users.

id

Used to find the UI element associated with this Rotor entry. This identifier should be used within a scrollView, either in a ForEach or using an id call.

textRange

Optional range of text associated with this Rotor entry. This should be a range within text that is set as the either label or accessibility value of the associated element.

prepare

Optional closure to run before a Rotor entry is navigated to, to prepare the UI as needed. This can be used to bring the UI element on-screen if it isn’t already, and SwiftUI is not able to automatically scroll to it.
