What types of links can be stored in the Side Table?

In the Side Table in iOS, weak and associated references can be stored. The Side Table is used to store additional data related to objects that do not fit directly into their structure, for example, to implement weak references or associations at runtime.

• Weak references: do not increase the reference count of an object, allowing to avoid cyclic dependencies.
• Associated objects: allow dynamically adding properties to objects at runtime, using the Side Table to store this data.

Thus, the Side Table serves as an auxiliary structure for storing such references, providing flexibility in memory management and object extensibility.
