One of the fun new features of iOS 18 is the ability to add special text effects to your messages. To use this feature, begin by selecting the text to be of emphasis, tap on the ‘A’ icon, and from the dropdown menu, select the desired animation effect which could either be a shake, and explode, among others. Also, the emphasized text can be bold, italic, and underlined concurrently. It is necessary to point out that for the recipient to witness the changes, he/she must have iOS 18.
