app extensions

App extensions are small software components that allow apps to share specific functionalities or information with other apps or system features on your device. They act like bridges, enabling one app to perform tasks or display content within the context of another app without needing to open separately. For example, a photo editing extension lets you edit images directly from your messaging app or photo gallery. This creates a more seamless and integrated user experience, allowing apps to work together efficiently and extend their capabilities beyond their primary interface.
