public struct PostLateUpdate

Remarks

PostLateUpdate
is the last phase in each iteration of the Player loop. Systems in this phase update canvases, audio, visual effects, renderers, and skinned meshes, render and present the frame, resume coroutines that yield WaitForEndOfFrame, and perform end-of-frame maintenance for input, memory, and the Profiler. In the Editor, Unity renders and presents the Game view, and resumes coroutines that yield WaitForEndOfFrame, outside the Player loop, so the systems that do this work in Players don't do anything in the Editor.
This struct identifies a phase of the Player loop. It has no members. In the default Player loop, the 
PlayerLoopSystem
for this phase contains a PlayerLoopSystem.subSystemList of native engine systems, each identified by one of the structs nested in this type.
Use this type with PlayerLoopSystem.type to find the phase when you add your own systems to it, or when you reorder, replace, or remove the systems it contains. If you remove or replace a native system, Unity no longer performs that system's work, so the related engine feature might stop working. Some native systems are active only in the Editor, only in Players, or only on platforms and configurations that support the related feature. Elsewhere, those systems remain in the Player loop but don't do anything.
For more information, refer to Customizing the Player loop and Order of execution for event functions.
