# framesPerSecond

The actual rate that the view controller attempts to call the view to update its contents.

## Declaration

```swift
var framesPerSecond: Int { get }
```

## Discussion

Discussion The view controller attempts to maintain this frame rate, but it may still drop frames if the per-frame processing performed by your application takes more time than the time between frames.
