How to write an image to a path in swift 3.0

I'm using core data to store a url to an image that was taken from the imagepicker.

So far I have the following: 

    let tempImage = info[UIImagePickerControllerOriginalImage] as? UIImage

    let image = UIImageJPEGRepresentation(tempImage!, 0.2)

    let path = try! FileManager.default.url(for: FileManager.SearchPathDirectory.documentDirectory, in: FileManager.SearchPathDomainMask.userDomainMask, appropriateFor: nil, create: false)
    let imageName = UUID().uuidString + ".jpg"

    let aPath = path.path

    let imagePath = (aPath as NSString).appendingPathComponent(imageName)

The result is now I have a path as a string to save in core data. But how do I write the image to the path? I was trying to use:

   let result = image!.writeToFile(path, atomically: true)

But i get an error saying value of type data has no member writeToFile. Is there another way to do it in swift 3.0?

Thanks for your help.

With help from Dylansturg,

I was able to rewrite my code to work. Here is the code for future reference:

do {
   let result = try image?.write(to: path, options: .atomic)
} catch let error { 
    print(error) 
}

In Swift 3, UIImageJPEGRepresentation creates Data instead of NSData. You can use write instead of writeToFile.

You should be able to use:

image.write(to: URL(fileURLWithPath: path), options: .atomic)

and write out your image data image to a file at path. Notice that it uses a URL instead of a string file path, and the options parameter has changed.

Maybe you can try to convert the UIImage object to NSData object, then follow this link to write the NSData object to a path:
