debugging▌

Network debugging identifies connectivity issues, latency problems, and data transmission errors that impact application performance.

Use these steps to deploy and diagnose app issues quickly.

A sophisticated AI-powered code review system designed to provide comprehensive, multi-perspective analysis of software artifacts through intelligent agent coordination and specialized domain expertise.

Mobile app debugging addresses platform-specific issues, device hardware limitations, and mobile-specific network conditions.

Accessibility Tree vs DOM: Visually hiding an element (e.g., CSS opacity: 0) behaves differently for screen readers than display: none or aria-hidden="true". The take_snapshot tool returns the accessibility tree of the page, which represents what assistive technologies "see", making it the most reliable source of truth for semantic structure.

Random fixes waste time and create new bugs. Quick patches mask underlying issues.

Check build environment BEFORE debugging code. Core principle 80% of "mysterious" Xcode issues are environment problems (stale Derived Data, stuck simulators, zombie processes), not code bugs.
