Swift 2 to Swift 3.0 motionManager

Question

I am converting an app from swift 2 to swift 3 and I\'m trying to use the CMMotionManager, but it gives me this error when I try to call the .startAccelerometerUpdates() functio

Answer 1

There are many changes in Swift3. Especially in expressions. Many NS suffix of types are removed such as NSError to Error, NSData to Data. Therefore, change NSError to Error. And if you want to prevent performance issue by multiple instances of CMMotionManager, use SwiftyMotionManager.
