How can I find a free volume capacity on iOS?

To find the free volume capacity on iOS, you can use the tools and techniques discussed in the session "Analyze heap memory" from WWDC 2024. This session covers various aspects of memory management, including measuring heap memory, dealing with transient and persistent growth, and fixing memory leaks.

Here are some steps you can follow:

1. Enable Malloc Stack Logging: This can be done in Xcode under the scheme diagnostics tab. This will help you track memory usage and identify where memory is being allocated.

2. Use Xcode's Memory Report: This tool shows an application's memory footprint over time, which includes the heap. It can help you identify large memory issues and track memory usage history.

3. Memory Graph Debugger: This tool captures memory graphs, showing all allocations and references between them. It can help you focus on specific allocations and understand why memory is being used.

4. Allocations Instrument: Use this to profile your app's heap. It records heap and virtual memory allocations, helping you identify memory spikes and analyze memory usage patterns.

For more detailed information, you can refer to the session "Analyze heap memory" and its chapters:

• Heap memory overview
• Tools for inspecting heap memory issues
• How the Xcode memory graph debugger works

These resources will guide you through the process of analyzing and optimizing your app's memory usage on iOS.
