Instance Method


Presents the drawable on the screen as soon as possible.



func present()


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 as soon as possible, but only after the command buffer has completed all render or write requests for that drawable.
