axiom-objc-block-retain-cycles

What problem does it solve?

This Skill systematically diagnoses and helps resolve memory leaks in Objective-C caused by block retain cycles, a common source of instability and crashes in iOS applications.

Core Features & Use Cases

• Diagnose Retain Cycles: Identifies circular references between objects and blocks using memory analysis tools.
• Apply Weak-Strong Pattern: Guides the implementation of the mandatory weak-strong pattern to break retain cycles.
• Handle Nested Blocks: Provides solutions for complex scenarios involving multiple nested blocks.
• Use Case: When a UIViewController fails to deallocate after being dismissed, and Instruments points to a block callback, this Skill provides the exact steps to find the cycle and fix it using the weak-strong pattern.

Quick Start

Use the axiom-objc-block-retain-cycles skill to diagnose a suspected memory leak in an Objective-C block.
