Swift Memory Management

Priority: P0

Implementation Guidelines

ARC Fundamentals

• Default: Strong references. Swift automatically manages retain/release.
• Weak: Use weak for delegate patterns and parent-child relationships.
• Unowned: Use unowned only when reference guaranteed to outlive (rare).

Capture Lists

• Closures: Always use [weak self] or [unowned self] in escaping closures.
• Self in Structs: No capture list needed (self is copied by value).
• Multiple Captures: [weak self, weak delegate].
