Run loop | Ask WWDC

The concept of a "run loop" is not explicitly mentioned in the provided context. However, there are related concepts discussed in the sessions from WWDC 2024 that involve loops and cycles in programming and debugging:

WebXR Frame Loop: In the session "Build immersive web experiences with WebXR," a frame loop is discussed. This loop involves rendering frames at a rate synced to the XR device, which is typically faster than a standard web browser's 60 frames per second. The loop is established by calling requestAnimationFrame to queue up actions for the next frame. This is similar to a run loop in that it continuously processes frames in a cycle.
Debugging Cycle in LLDB: In the session "Run, Break, Inspect: Explore effective debugging in LLDB," the debugging cycle is described as a "run, break, inspect" loop. This involves running the program, breaking at certain points to inspect the state, and then continuing execution. This cycle is crucial for effective debugging.
Render Loop in visionOS: In the session "Render Metal with passthrough in visionOS," a render loop is described, consisting of an update stage and a submission stage. This loop is used to update logic and render results, similar to a run loop in its iterative processing of tasks.
