A mapping application, for instance, may depend on a recent location services API not available in iOS 12.5.7, rendering it unusable or with reduced functionality.
-
Binary Compatibility
Applications are compiled into binary code specific to an operating system and architecture. Changes in the iOS architecture over time can lead to binary incompatibility. While iOS generally maintains backward compatibility to a degree, applications compiled exclusively for newer architectures may not execute on iOS 12.5.7. This is typically less common, but can still occur with apps utilizing very recent processor-specific instructions.
-
Minimum Deployment Target
Developers specify a minimum deployment target when building an application, indicating the oldest iOS version the application supports. If the deployment target is set higher than iOS 12.5.7, the App Store prevents installation on devices running this version. This mechanism ensures that users do not attempt to install applications known to be incompatible.
-
Resource Requirements
Newer applications often demand increased processing power, memory, and storage resources. Devices running iOS 12.5.7, typically older models, may lack the necessary hardware capabilities to run these applications efficiently. Even if the application technically installs, performance may be severely degraded, leading to a poor user experience. A graphically intensive game, for example, could be unplayable due to frame rate issues or memory limitations.
The interplay of API availability, binary structure, deployment targets, and resource requirements dictates the extent to which applications function on iOS 12.5.7.
