Can you explain how the runtime environment functions in your system?

The runtime environment in iOS is a set of components that ensure the execution of applications on the device. It includes:

• The iOS operating system kernel, which manages device resources.
• The Objective-C or Swift runtime, responsible for memory management, dynamic class loading, exception handling.
• Cocoa Touch frameworks, providing APIs for user interface, networking, multimedia, etc.

When an application starts, the runtime loads its code, allocates memory, initializes objects, and facilitates interaction with the system. For example, ARC (Automatic Reference Counting) automatically manages object lifetimes, freeing memory when objects are no longer needed.

Thus, the runtime environment ensures stable and efficient operation of applications on iOS.
