# startGyroUpdates(to:withHandler:)

Starts gyroscope updates on an operation queue and with a specified handler.

## Declaration

```swift
func startGyroUpdates(to queue: OperationQueue, withHandler handler: @escaping CMGyroHandler)
```

## Parameters

- `queue`: An operation queue provided by the caller. Because the processed events might arrive at a high rate, using the main operation queue is not recommended.
- `handler`: A block that is invoked with each update to handle new gyroscope data. The block must conform to the doc://com.apple.coremotion/documentation/CoreMotion/CMGyroHandler type.

## Discussion
