Q1Domain Verified
Within the context of Swift's Automatic Reference Counting (ARC), what is the primary mechanism that enables an object to remain in memory as long as there are active references to it?
Weak references
Deinitialization
Strong reference cycles
Reference counting
Q2Domain Verified
Consider a scenario where a class `Parent` has a strong reference to an instance of class `Child`, and `Child` also has a strong reference back to `Parent`. What is the most likely consequence of this arrangement under Swift's ARC?
The `Child` instance will be deallocated, but the `Parent` instance will remain in memory.
Both `Parent` and `Child` instances will be deallocated correctly when they go out of scope.
A strong reference cycle will form, preventing both `Parent` and `Child` from being deallocated, leading to a memory leak.
The `Parent` instance will be deallocated, but the `Child` instance will remain in memory.
Q3Domain Verified
In Swift, when would you typically use a `weak` reference to break a strong reference cycle between two objects?
When both objects are of equal importance and should always coexist.
When one object is the primary owner and the other is a temporary delegate or observer.
When you want to ensure that the weakly referenced object is always available.
When you are dealing with value types (structs or enums).
