The process involves transferring and installing an iOS Package Archive file onto an iPhone. This file type, commonly used for distributing iOS applications, contains the app’s data and resources. Installing these files allows users to deploy applications that are not available on the App Store or are in development.
The ability to install applications outside of the official App Store offers several advantages. It allows developers to test beta versions of their apps with a select group of users. Furthermore, it enables users to access apps that may not meet Apple’s guidelines for inclusion in the App Store, potentially offering niche functionalities or content. Historically, this capability has been vital for app development and distribution before official App Store submission.
