Get Facebook profile picture from URL - swift

Question

I want to upload the profile picture from Facebook to Firebase. I tried this answer: Upload Facebook image URL to Firebase Storage
However, Swift is giving me errors on the third line of code of that answer. The code is:
let dictionary = result as? NSDictionary
let data = dictionary?.object(forKey: "data")
let urlPic = (data?.objectForKey("url"))! as! String
Swift is telling me: Cannot call value of non-function type 'Any?!' after I changed the code to what Swift keeps suggesting me:
let urlPic = ((data as AnyObject).object(ForKey: "url"))! as! String
What is the code to use when I want to retrieve the profile picture from Facebook? My goal is to also store it into Firebase, but that will come after I get the profile picture first.

Answer 1

The answer is in Swift 1.2
I took reference here and implemented also
You can do this:
// accessToken is your Facebook id
func returnUserProfileImage(accessToken: NSString)
{
var userID = accessToken as NSString
var facebookProfileUrl = NSURL(string: "http://graph.facebook.com/\(userID)/picture?type=large")
if let data = NSData(contentsOfURL: facebookProfileUrl!) {
imageProfile.image = UIImage(data: data)
}
}
This is the way I got Facebook id:
func returnUserData()
{
let graphRequest : FBSDKGraphRequest = FBSDKGraphRequest(graphPath: "me", parameters: nil)
graphRequest.startWithCompletionHandler({ (connection, result, error) -> Void in
if ((error) != nil)
{
// Process error
println("Error: \(error)")
}
else
{
println("fetched user: \(result)")
if let id: NSString = result.valueForKey("id") as? NSString {
println("ID is: \(id)")
self.returnUserProfileImage(id)
} else {
println("ID es null")
}
}
})
}
