Declaration

func present(afterMinimumDuration duration: CFTimeInterval)

Parameters

Discussion

Graphics and compute commands can schedule render or write requests to a given drawable. A drawable tracks whether it has outstanding render or write requests on it and will not present until those requests have been completed.

In this case, the drawable's presentation occurs after waiting for the previous drawable to meet the minimum display time and after the command buffer has completed all render or write requests for that drawable.
