SwiftUI Debugging

About

SwiftUI Debugging empowers developers to move past trial-and-error by providing a structured framework for diagnosing xOS interface issues. It categorizes common problems into view updates, preview stability, and layout logic, offering systematic decision trees to isolate root causes like struct mutation, lost binding identity, or missing observer patterns. With specific guidance on modern tools like Self._printChanges() and the iOS 17+ @Observable macro, this skill helps developers avoid common pitfalls and maintain high-performance, reactive UIs even under tight deadlines.
