How do I set up custom LLDB aliases using this skill?

The guide provides a dedicated section on .lldbinit customization with pre-made aliases for flushing UI changes (CATransaction flush) and printing auto-layout traces.

Can I use this skill for Objective-C projects?

Yes, the reference includes specific syntax and flags for evaluating expressions in both Swift and Objective-C, including low-level UI debugging tools like recursiveDescription.

What is the difference between v, p, and po in this guide?

The guide explains that 'v' (frame variable) reads memory directly without compilation (best for Swift values), 'p' evaluates expressions via the compiler, and 'po' provides the object description using debugDescription.

Does it cover SwiftUI-specific debugging?

Yes, it includes specialized commands like Self._printChanges() and techniques for inspecting SwiftUI @State backing stores using underscore prefixes.

Mobile Development

Provides a comprehensive, task-oriented LLDB command reference for debugging modern iOS, iPadOS, watchOS, and tvOS applications.

The axiom-lldb-ref skill serves as a high-performance lookup for developers debugging Apple platforms. It organizes LLDB's complex command set into logical categories like variable inspection, breakpoint management, and memory manipulation, offering specific flags and syntax for both Swift and Objective-C contexts. By integrating this into Claude Code, developers can instantly recall the exact syntax for advanced debugging tasks—such as conditional breakpoints, watchpoints, or SwiftUI-specific state inspection—without leaving their terminal workflow.
