In which part of the application's lifecycle is the automatic garbage collector (ARC) used?

Automatic Reference Counting (ARC) in iOS is applied throughout the application's lifecycle. It automatically manages memory by freeing objects that are no longer in use to prevent memory leaks. ARC works at compile time by inserting retain and release calls, and during runtime, these calls manage the lifetime of objects. This way, developers do not need to manually manage memory, which simplifies development and increases application stability.
