XCode8 Swift3 で iOS 9.3 用加速度センサー値取得のサンプルアプリ

import UIKit
import CoreMotion

class ViewController: UIViewController {

    // MotionManager
    let motionManager = CMMotionManager()

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.

        if motionManager.isAccelerometerAvailable {
            // 加速度センサーの値取得間隔
            motionManager.accelerometerUpdateInterval = 0.1

            // motionの取得を開始
            motionManager.startAccelerometerUpdates(to: OperationQueue.current!, withHandler: { (data, error) in
                // 取得した値をコンソールに表示
                print("x: \(data?.acceleration.x) y: \(data?.acceleration.y) z: \(data?.acceleration.z)")
            })
        }
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }
