Parse data in swift - swift

Question

I have a "Users" table and a "cDetails" table. Inside cDetails table I have a field called "full_name". I am trying to retrieve and output the value in this table based on the current user that is logged in.
In the cDetails table I have a field called "createdBy" which points to the objectID in the Users table that created it.
This is all I have so far:
let query = PFQuery(className: "cDetails")
let currentUser = PFUser.currentUser()
query.includeKey("full_name")
query.whereKey("createdBy", equalTo: currentUser!.objectId!)
print("CREATED BY " + PFUser.currentUser()!.objectId!);
query.findObjectsInBackgroundWithBlock {
(objects, error) -> Void in
if objects == nil {
print(objects)
print("called")
// self.full_nameLabel.text = "\(query)"
} else {
print("FAILED")
}
}

My approach:
let query = PFQuery(className: "cDetails")
let currentUser = PFUser.currentUser()
query.includeKey("full_name")
query.whereKey("createdBy", equalTo: currentUser!.objectId!)
print("CREATED BY " + PFUser.currentUser()!.objectId!);
query.findObjectsInBackgroundWithBlock {
(objects, error) -> Void in
if **objects == nil** {
print(objects)
print("called")
// self.full_nameLabel.text = "\(query)"
} else {
print("FAILED")
}
}
You are looking whether objects == nil. You want to have your error == nil and your objects != nil
After that proceed with
for object in objects {
let fullName = object["full_name"] as! String
}
