Cannot convert value of type FBSDKGraphRequestHandler - ios

Question

I'm getting the following error when I try to make a data request using the Facebook SDK:
Cannot convert value of type '(_,_,_) throws -> Void' to expected argument type 'FBSDKGraphRequestHandler!'
Here is the relevant code where the error is occurring. I found this in a tutorial but I think it worked with older versions of XCode. I'm using the latest version 7.2.1.
UPDATED
let graphRequest = FBSDKGraphRequest(graphPath: "me", parameters: ["fields": "id, name, gender, email"])
graphRequest.startWithCompletionHandler ({ [weak self] connection, result, error in
if error != nil {
//onError()
print(error)
return
} else {
//get results
PFUser.currentUser()?["gender"] = result["gender"]
PFUser.currentUser()?["name"] = result["name"]
try PFUser.currentUser()?.save()
let userId = result["id"] as! String
let facebookProfilePictureUrl = "https://graph.facebook.com/" + userId + "/picture?type=large"
if let fbpicUrl = NSURL(string: facebookProfilePictureUrl) {
if let data = NSData(contentsOfURL: fbpicUrl) {
self.profilePic.image = UIImage(data: data)
let imageFile:PFFile = PFFile(data: data)!
PFUser.currentUser()?["image"] = imageFile
try PFUser.currentUser()?.save()
}
}
}
})
Thanks!

I hope you are using the latest FBSDK in that the completionHandler: has been changed. See the below code:
let graphRequest = FBSDKGraphRequest(graphPath: "me", parameters: param)
graphRequest.startWithCompletionHandler { [weak self] connection, result, error in
if error != nil {
//onError()
print(error.description)
return
}else{
let fbResult = result as! Dictionary<String, AnyObject>
//Do You rest of the code here
}
})
