How will the system behave if the data structure reaches its limit and becomes overflowed?

If the data structure in an iOS application (such as an array, dictionary, or queue) reaches its limit and overflows, the behavior depends on the type of structure and how it is used.

• For standard Swift collections (Array, Dictionary), overflow usually does not occur because they dynamically expand in memory.
• If a fixed size is used (for example, an array with a limit or a circular buffer), new data may not be added or may overwrite old data once the limit is reached, depending on the implementation.
• In case of memory overflow (for example, too large data volume), the application may receive an out of memory error and crash.

It is important to control the size of structures and free unused data to avoid overflow and crashes.
