What’s the difference between hangs and hitches?

The difference between hangs and hitches can be understood in the context of performance issues in applications:

• Hangs: These are typically more severe and prolonged interruptions where the application becomes unresponsive for a noticeable period. This can be due to various reasons such as deadlocks, long-running operations on the main thread, or waiting for a resource that is not available.

• Hitches: These are shorter, more transient interruptions that cause brief pauses or stutters in the application's performance. Hitches can occur due to minor delays in processing, such as garbage collection, brief network latency, or small spikes in CPU usage.

2. Run, Break, Inspect: Explore effective debugging in LLDB - This session covers techniques for handling high-firing breakpoints, which can be useful in diagnosing performance issues like hangs and hitches.

These sessions provide a comprehensive look at how to identify and address performance bottlenecks in your applications.
