In the context of debugging and development, "glitches" typically refer to unexpected behaviors or bugs in the software that cause it to function incorrectly. These can be due to various reasons such as misconfigured components, memory issues, or incorrect transformations in a 3D scene.
For example, in the session Break into the RealityKit debugger, common bugs in RealityKit apps are discussed, including issues with entity hierarchies and transformations that can lead to unexpected behaviors. The RealityKit debugger is introduced as a tool to help catch and fix these bugs.
Similarly, in the session Analyze heap memory, memory spikes are discussed as a type of transient memory growth that can cause performance issues and even app termination.
These sessions provide tools and techniques to identify and resolve such glitches, ensuring a smoother and more reliable app performance.
Run, Break, Inspect: Explore effective debugging in LLDB
Learn how to use LLDB to explore and debug codebases. We’ll show you how to make the most of crashlogs and backtraces, and how to supercharge breakpoints with actions and complex stop conditions. We’ll also explore how the “p” command and the latest features in Swift 6 can enhance your debugging experience.
Create custom hover effects in visionOS
Learn how to develop custom hover effects that update views when people look at them. Find out how to build an expanding button effect that combines opacity, scale, and clip effects. Discover best practices for creating effects that are comfortable and respect people’s accessibility needs.
Break into the RealityKit debugger
Meet the RealityKit debugger and discover how this new tool lets you inspect the entity hierarchy of spatial apps, debug rogue transformations, find missing entities, and detect which parts of your code are causing problems for your systems.
Build a spatial drawing app with RealityKit
Harness the power of RealityKit through the process of building a spatial drawing app. As you create an eye-catching spatial experience that integrates RealityKit with ARKit and SwiftUI, you’ll explore how resources work in RealityKit and how to use features like low-level mesh and texture APIs to achieve fast updates of the users’ brush strokes.
Xcode essentials
Edit, debug, commit, repeat. Explore the suite of tools in Xcode that help you iterate quickly when developing apps. Discover tips and tricks to help optimize and boost your development workflow.
Analyze heap memory
Dive into the basis for your app’s dynamic memory: the heap! Explore how to use Instruments and Xcode to measure, analyze, and fix common heap issues. We’ll also cover some techniques and best practices for diagnosing transient growth, persistent growth, and leaks in your app.
