wait(until:tolerance:)
Blocks the current thread until the specified time.
Declaration
func wait(until deadline: LayerRenderer.Clock.Instant, tolerance: Duration? = nil)Parameters
- deadline:
The Mach absolute time at which to wake up the thread. Typically, you supply one of the predicted times associated with the current frame, such as the optimal input time.
- tolerance:
The amount of time before or after the deadline to allow the system to wake up the thread. Specifying a non-zero value lets the system shift the actual deadline to coalesce other work and achieve greater power savings.

Use this function to block your render loop while waiting for critical time events. For example, use it to block the thread prior to starting the submission phase for a given frame.
