如何在swift中使用陀螺仪

import UIKit
import CoreMotion

class ViewController: UIViewController {
    
    let motionManager = CMMotionManager()
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        if motionManager.isGyroAvailable {
            motionManager.gyroUpdateInterval = 0.2
            motionManager.startGyroUpdates(to: OperationQueue.main) { (data, error) in
                guard let gyroData = data else { return }
                
                print("Rotation Rate X: \(gyroData.rotationRate.x)")
                print("Rotation Rate Y: \(gyroData.rotationRate.y)")
                print("Rotation Rate Z: \(gyroData.rotationRate.z)")
            }
        } else {
            print("Gyroscope is not available.")
        }
    }
    
    override func viewWillDisappear(_ animated: Bool) {
        super.viewWillDisappear(animated)
        motionManager.stopGyroUpdates()
    }
}
