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.
Improve memory usage and performance with Swift
Discover ways to improve the performance and memory management of your Swift code. We’ll explore ways to refine your code – from making high-level algorithmic changes to adopting the new InlineArray and Span types for finer control over memory and allocations.
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.
