# nextFrameTime()

Returns the time at which the next update should happen.

## Declaration

```swift
func nextFrameTime() -> CFTimeInterval
```

## Return Value

Return Value The time at which the next update should happen.

## Discussion

Discussion If infinite, no update needs to be scheduled yet. If nextFrameTime is the current frame time, a continuous animation is running and an update should be scheduled after an appropriate delay.
