The process allows users to obtain and install applications on Apple mobile devices without relying solely on the official App Store. This typically involves obtaining a signed application package and utilizing a compatible installation method. As an example, a developer might use this to deploy test versions of an app to a limited group of users before public release.
This capability offers increased flexibility in app distribution and usage. It can circumvent geographical restrictions, enable access to applications not approved for the App Store, or facilitate the deployment of internal enterprise applications. Historically, methods for sideloading applications have been limited or restricted by Apple, often requiring developer accounts or specific device configurations.
