How does the presence of a Side Table affect the lifespan of an object in the system?

In iOS, a Side Table is a mechanism that allows associating additional data with an object without changing its class. The presence of a Side Table affects the object's lifetime as follows:

• The Side Table stores additional data related to the object, and this data lives as long as the object itself.
• If the object is deallocated, the data associated with it in the Side Table is also removed.
• Therefore, the Side Table does not extend the object's lifetime but extends its state without altering its structure.

This is useful, for example, for implementing dynamic properties or storing metadata without directly affecting the object's memory management.
