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

You must call stopGyroUpdates() when you no longer want your app to process gyroscope updates.
