A common archive file type associated with Apple’s mobile operating system serves as a means to distribute applications for devices running that OS. It contains the binary for the application, along with resources and metadata. As an example, when an application is prepared for submission to the App Store or for ad-hoc distribution, it is packaged into this specific archive format.
This package format streamlines application deployment, offering a single, self-contained unit for installation. Its consistent structure ensures proper application installation and execution on compatible devices. Historically, it has played a critical role in the evolution of the iOS application ecosystem, facilitating both commercial distribution through the App Store and internal distribution within organizations.
