I'm sorry, but the context provided does not contain specific information about the behavior of NSManagedObject and setting an empty array in different iOS versions. However, I can provide some general insights into Swift and memory management from the sessions mentioned.

In Swift, arrays are value types, which means they are copied when assigned to a new variable or passed to a function. This behavior is managed through a mechanism called "Copy on Write," which optimizes memory usage by delaying the actual copying of the array until it is modified. This is discussed in the session Improve memory usage and performance with Swift.

If you are dealing with NSManagedObject and Core Data, the behavior might differ due to how Core Data manages its objects and relationships. Core Data uses reference types and manages memory differently, which could lead to differences in behavior across iOS versions.

For more detailed information, you might want to look into specific Core Data documentation or forums that discuss changes in Core Data behavior across iOS versions.
