SwiftUI Debugging Diagnostics

关于

This diagnostic skill offers a structured approach to solving the most stubborn SwiftUI bugs, ranging from intermittent 'heisenbugs' to performance-sapping redundant view updates. It leverages advanced tools like Xcode 26+ Instruments and Self._printChanges() to map data flow, verify view identity, and audit environment dependencies. Whether you're dealing with mysterious preview crashes or state resets, this skill provides production-grade protocols to move beyond trial-and-error and into systematic resolution for modern iOS, iPadOS, watchOS, and tvOS development.
