How to access profile picture with Facebook API in Swift 3?

Earlier I tried to access like this:

let gr2 : FBSDKGraphRequest = FBSDKGraphRequest(graphPath: "me", parameters: ["fields": "id,picture.width(198).height(198)"])
gr2.start(completionHandler: { (connection, result2, error) -> Void in                
let data = result2 as! [String : AnyObject]
let _loggedInUserSettingRecordName = data["id"] as? String // (forKey: "id") as? String
let profilePictureURLStr = data["picture.data.url"] as? String

But profilePictureURLStr is nil now. What is different with Swift 3?

I can see url info is part of it:

(lldb) po result2
▿ Optional<Any>
  ▿ some : 2 elements
    ▿ 0 : 2 elements
      - .0 : id
      - .1 : 10208273026137463
    ▿ 1 : 2 elements
      - .0 : picture
      ▿ .1 : 1 element
        ▿ 0 : 2 elements
          - .0 : data
          ▿ .1 : 4 elements
            ▿ 0 : 2 elements
              - .0 : is_silhouette
              - .1 : 0
            ▿ 1 : 2 elements
              - .0 : height
              - .1 : 200
            ▿ 2 : 2 elements
              - .0 : url
              - .1 : https://scontent.xx.fbcdn.net/v/t1.0-1/p200x200/13418946_10208553701714177_3969269576626117653_n.jpg?oh=add39246ec9693ecead0529ecbbbfc53&oe=5862D7ED
            ▿ 3 : 2 elements
              - .0 : width
              - .1 : 200

    I tried many possibility, and this way you can get the url:

    let profilePictureURLStr = (data["picture"]!["data"]!! as! [String : AnyObject])["url"]

  2. 0

    Also this way works in Swift 3:

    if let picture = data["picture"] as? Dictionary<String,Any> {
                        if let data = picture["data"] as? Dictionary<String,Any> {
                            if let pictureUrl = data["url"] as? String {
                                dict["remote_main_image_url"] = pictureUrl
                            }
                        }
                    }
