A compressed archive containing an iOS application, this file type is the standard distribution method for apps on Apple’s mobile operating system. It includes the application binary, resources, and necessary metadata required for installation on an iPhone, iPad, or iPod Touch. As an example, imagine a developer completing work on a new game. They would create this type of archive to share it with testers or to submit it to the App Store.
These files are crucial for application deployment outside of the official App Store. This sideloading capability allows developers to test their apps thoroughly before release, distribute custom apps to internal teams, or provide beta versions to select user groups. Historically, this capability has enabled greater flexibility for developers and end-users alike, circumventing the stringent review process of the App Store in specific, controlled environments. It’s important to understand the specific uses and advantages, as it allows a level of control not possible with solely App Store distributed apps.
