Software applications designed to function correctly on Apple mobile devices operating with the iOS version 10.3.4 are specifically tailored to the constraints and capabilities of that operating system. These applications must adhere to the APIs and frameworks available within that iOS version to ensure proper execution and user experience. For example, a navigation app, a game, or a productivity tool might be engineered to run smoothly on an iPhone or iPad using iOS 10.3.4.
The significance of applications targeting this specific iOS version lies in maintaining functionality for users who have older devices that cannot be upgraded to more recent operating systems. These users continue to rely on their existing hardware and the applications it supports. Historically, older iOS versions eventually lose support from developers as they focus on newer technologies, but a selection of apps often remains functional, allowing continued usability of legacy devices.
