What problem does it solve?

This Skill helps developers identify and resolve performance bottlenecks, memory leaks, crashes, and build failures in iOS applications.

Core Features & Use Cases

• Runtime Debugging: Utilize LLDB for step-by-step code inspection, breakpoint management, and expression evaluation.
• Memory Analysis: Employ the Memory Graph Debugger and Instruments (Allocations, Leaks) to detect and fix memory issues like retain cycles.
• Performance Profiling: Use Instruments (Time Profiler, Core Animation, SwiftUI) to pinpoint CPU, rendering, and UI performance problems.
• Build Triage: Understand and resolve compiler errors and dependency conflicts.
• Use Case: Your app is experiencing slow scrolling in a list. Use this Skill to profile the list with Instruments' Time Profiler and SwiftUI templates to find the cause of the slowdown.

Quick Start

Use the debugging-instruments skill to analyze memory usage in your app by running the Allocations template in Instruments.
