Type 'Any' Has No Subscript Members in Facebook SDK

Question

I was integrating Facebook Login SDK, in my app and I am new to this. I implemented it, but now I want to get the email. So, following the tutorial I created the same function as the tutorial showcased.

Here is the function:

func fetchProfile()
{
    print("Fetch Profile")

    let parameters: [String : Any] = ["fields" : "email, first_name, last_name, picture.type(large)"]

    FBSDKGraphRequest(graphPath: "me", parameters: parameters).start(completionHandler: {

        (connection, result, error) -> Void in

        if error != nil {

            print(error!)

            return
        }

        if let email = result["email"] as? String {

            print(email)

        }   
    }
}

So, the programmer was using Swift 3 there and I am using Swift 4 here, so is it creating any issue? And, it says Type "Any" has no subscript members where if let email = is written. How to solve this?

Answer 1

cast result to [String:Any]

if let resultDict = result as? [String:Any]{
   if let email = resultDict["email"] as? String  {
            print(email)
        }
}
