iOS 18: Use Emoji as Tapback Reactions in Messages

iOS 18 brings significant updates to Apple's Messages app, particularly enhancing the Tapback feature. The six standard Tapback icons now boast vibrant colors and intricate details, making reactions more expressive. Crucially, emoji support has been added, allowing users to choose from a vast library of characters to convey reactions more personally and specifically. To use emoji Tapbacks, long-press on a message, swipe left on the standard reactions, and select an emoji or tap the greyed-out emoji to access the emoji keyboard. The Messages app in iOS 18 also includes new text effects and formatting options, such as undo send, scheduled send, and rich link previews.
