To learn about profiling your iOS app, you should consider watching the following sessions from WWDC:

  1. Profile and optimize power usage in your app - This session provides insights into using the Power Profiler in Instruments to analyze and optimize your app's power consumption. It covers both reproducible issues and hidden issues that might occur in real-world scenarios. You can start with the chapter on Debug reproducible issues.

  2. Optimize SwiftUI performance with Instruments - This session focuses on using the SwiftUI instrument to diagnose and improve the performance of SwiftUI apps. It includes practical examples of profiling and optimizing SwiftUI views. You can start with the chapter on Discover the SwiftUI instrument.

  3. Optimize CPU performance with Instruments - This session is dedicated to optimizing CPU performance using Instruments, specifically for Apple silicon CPUs. It provides a deep dive into CPU profiling and bottleneck analysis. You can start with the chapter on Profilers.

These sessions will give you a comprehensive understanding of different aspects of profiling and optimizing your iOS app using Instruments.

Profile and optimize power usage in your app

Learn how to optimize your app for maximum battery life. Discover how to identify the root cause of power issues in your app — whether you can reproduce the issue while connected to Xcode or on the go. Find out how to measure power use so you can make better decisions about new features and proactively build more efficient apps.
