Summary of Content from WWDC Sessions

Explore the Swift on Server ecosystem

  • Observability: This session discusses the importance of observability in server-side Swift applications. It covers logging, metrics, and tracing to help troubleshoot issues like PSQL errors that do not provide detailed information by default. Adding observability can help identify and resolve such errors effectively.

Xcode essentials

  • Testing and Debugging: This session highlights the depth of data available in test reports, including summaries and detailed results of test runs. It emphasizes the usefulness of screen recordings and timelines to pinpoint failures. It also suggests starting with the "Testing your apps and Xcode" documentation and the session "Meet Swift testing."

Run, Break, Inspect: Explore effective debugging in LLDB

  • Crash Logs and Backtraces: This session explains how to use LLDB to debug crashes by examining crash logs and backtraces. It demonstrates how to set breakpoints, navigate to source code locations, and use variable viewers to understand the state of the program at the time of the crash.
  • Breakpoint Actions: It also covers setting breakpoints and using them to investigate issues by relaunching the program without recompiling, saving time during debugging.

Discover media performance metrics in AVFoundation

  • Media Playback Issues: This session focuses on diagnosing media playback stalls in AVFoundation. It shows how to use timeline events and NSURLSessionTaskMetrics to understand issues like HTTP 404 errors that cause playback stalls.

Enhance your UI animations and transitions

  • UIKit and SwiftUI Animations: This session covers the lifecycle of view controllers in UIKit and how callbacks work during transitions. It also discusses new transitions in SwiftUI and provides tips for animating representables and gesture-driven animations.

Explore object tracking for visionOS

  • Object Tracking and Coaching UI: This session demonstrates how to use RealityKit API to implement object tracking and coaching UI in visionOS. It includes steps to display a preview 3D model and add virtual labels to guide users.
