AttributeScopes.AccessibilityAttributes.HeadingLevelAttribute

enum · iOS 15.0+ · SDK 27.1

@frozen enum HeadingLevelAttribute

An attribute for the level of this heading. Assistive technologies can use this property to improve navigation and describe the level number of levels ``HeadingLevel/h1`` through ``HeadingLevel/h6`` alongside the text. For example, you can rank sections within UI using a heading level. The most important section is marked with``HeadingLevel/h1``. Nested sections can use subsequent heading levels. For unranked headings, use ``HeadingLevel/unspecified``.
