![]() ![]() ![]() The following example shows a list with a Default badge on one of its rows. This modifier creates a Text view on your behalf, and treats the localized key similar to init (:). Badges only appear in list rows and tab bars. Keep the contents of the badge as short as possible. Finally, if no to-dos exist for that card, no badge is shown. Use a badge to convey optional, supplementary information about a view. ![]() onChange modifiers since the Published property is referenced directly.
