Improve your SwiftUI app's performance with Xcode 26

Pol Piella Abadia

A hands-on introduction to Xcode 26 instruments tailored towards diagnosing and fixing SwiftUI performance problems.

Have you ever spent hours trying to diagnose UI hangs or hitches, or received user feedback about your app feeling sluggish on certain devices? And when you did, did you ever feel like you didn’t know where to start?You’re not alone! I’ve spent much of my career working on products where performance was key to their success, and over time I’ve learned how to identify and fix the subtle (and not-so-subtle) bottlenecks that make native Apple apps stutter. In this workshop, I’ll share the techniques, workflows, and tools that have saved me countless hours — and made my apps feel silky-smooth.Join me as we dive deep into SwiftUI performance debugging using the latest industry standard technologies. You’ll walk away with a solid understanding of how to analyze performance data, recognize common patterns that lead to UI jank, and apply practical fixes that actually move the needle.<h3>Workshop Contents</h3><ul><li>Introduction to Xcode Instruments</li><li>What’s new in Xcode 26’s performance tools</li><li>Demo app walkthrough and analysis</li><li>Diagnosing and fixing real-world SwiftUI performance issues</li></ul>By the end, you’ll not only know how to fix performance problems — you’ll know why they happen, and how to design your SwiftUI apps to avoid them altogether.You will also take a full demo project, slides and notes that you can go through at home.
