# frameTiming

The timing information for the drawable’s frame.

## Declaration

```swift
var frameTiming: LayerRenderer.Frame.Timing { get }
```

## Mentioned in

Drawing fully immersive content using Metal

## Discussion

Discussion This retrieves a frame’s timing information from a drawable instance that represents that frame. For Swift, it’s an alternative to calling a frame’s predictTiming() method. For ObjectiveC, it’s an alternative to calling the cp_frame_predict_timing function. In ObjectiveC, you can determine when to start updating your data structures by passing a cp_frame_timing_t instance to the cp_frame_timing_get_optimal_input_time function.
