The ability to capture the visual output of an iPhone or iPad is a built-in feature on iOS devices. It allows users to create video recordings of their on-screen activity, often for demonstration, tutorial, or documentation purposes. For example, this functionality enables someone to illustrate app usage, troubleshoot technical issues, or archive ephemeral content.
This capability offers significant advantages. It facilitates communication by providing a clear, visual method for conveying information that might otherwise be difficult to explain. Its integration within the operating system means it is readily accessible without the need for third-party applications. Previously, such recording necessitated external software or hardware, adding complexity and potential cost.
