Swift querying Parse all objects in class - swift

Question

I have an app that I need to grab all values in the class. I need to get "players" and "total" from the class "runningTotal". Here is the code I have:
var query = PFQuery(className:"runningTotal")
query.selectKeys(["players", "total"])
query.findObjectsInBackgroundWithBlock
{
(objects: [AnyObject]!, error: NSError!) -> Void in
if error == nil
{
self.test = objects[0]["total"]
}
}
I want to set a variable (test) equal to the result of total. I would also want to do this with players. I don't think the above code is right, as it doesn't work. I obviously don't need any constraints as I want to fetch all of the results from this class. How would I go about solving this?
Thanks for any help in advance!

As long as your query is error free, you'll need to iterate through the objects array. As you iterate through each object, which will be of type AnyObject, you will need to cast the object as a PFObject. Then you will be able to grab the data you require from it.
var query = PFQuery(className:"runningTotal")
query.findObjectsInBackgroundWithBlock {
(objects: [AnyObject]!, error: NSError!) -> Void in
if error == nil{
for object in objects{
if let data = object as! PFObject{
//Set test to total (assuming self.test is Int)
self.test = data["total"] as! Int
}
}
}else{
//Handle error
}
}
