iOS is Apple’s mobile operating system used on the iPhone. It provides the software environment in which mobile applications run and defines how apps interact with the device, system services, security features, notifications, storage, and other functionality. Applications developed for iOS are typically distributed to users through the App Store.
Businesses creating a mobile app need to consider the operating systems their customers use. Supporting iOS allows an application to reach iPhone users and use capabilities provided by Apple devices. The platform also has specific requirements for application development, testing, distribution, and App Store review that need to be considered before publication.
A company creates a mobile application for its customers and makes an iOS version available for iPhone users. After testing and completing the required publishing process, the application is distributed through the App Store.
