Swift Automatic Reference Counting Questions

Focuses on memory management in Swift using Automatic Reference Counting. Topics include how reference counting works, strong references and ownership, retain cycles and reference cycles in object graphs, detecting and breaking cycles with weak and unowned references, closure capture semantics and capture lists, lifetime and scope considerations for long lived objects, bridging to other runtimes such as Objective C, and practical debugging and profiling strategies using platform tools to find leaks and excessive memory usage. Candidates should be comfortable explaining when to use weak versus unowned, patterns to avoid common leaks, and strategies to design object relationships to minimize retention problems.
