# isLowLatencyEventDispatchConfirmed A Boolean value that indicates whether the system runs low-latency phases for the UI update. ``` var isLowLatencyEventDispatchConfirmed: Bool { get } ``` ## Discussion The value of this property is when the system runs low-latency event dispatch during the UI update. Use this information to determine whether to avoid doing the same work more than once. For example, when considering whether to render a pencil-drawing stroke in [`afterEventDispatch`](/documentation/UIKit/UIUpdateActionPhase/afterEventDispatch), if this property is `true`, but [`isPerformingLowLatencyPhases`](/documentation/UIKit/UIUpdateInfo/isPerformingLowLatencyPhases) is `false`, you might consider waiting until after low-latency event dispatch to render the stroke. This value can change from `false` to `true` during the UI update, but not from `true` to `false`. > Important: > Checking the value of this property can cause the system to commit to low-latency event dispatch unnecessarily. Check this property only when you have an intention to act on its value. --- Copyright © 2026 Apple Inc.
