I've been able to save successfully to Parse via Swift, but am having trouble retrieving data (and all of the tutorials on retrieving seem to be for Obj-C).
Here's my code (with Id's redacted).
Parse.setApplicationId("XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX", clientKey: "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX")
var query = PFQuery(className: "EventObject")
query.getObjectInBackgroundWithId(objectId: String!) {
(event: PFObject!, error: NSError!) -> Void in
if error == nil {
println(event)
} else {
println(error)
}
}
I have 4 records in this class right now, but if I want to pull the data for all of them, how do I get the Object using the ID if I'm not sure what the IDs are? I'm assuming I can access them sequentially as an array, but I'm not quite clear how to do that, and am confused, as the only command I know to retrieve appears to require knowing the ID.
Thanks for any help!

let adventureObject = PFQuery(className: "ClassName")
adventureObject.addAscendingOrder("objectId")
var objectID: String = String()
adventureObject.findObjectsInBackground(block: { (Success, error) in
})

Here is the code for fetch objects in Swift3.0.
let query = PFQuery(className: "Your_Class_Name")
query.findObjectsInBackground { (objects, error) in
if error == nil {
}
else {
}
}

Swift 2.1 Update
func fetchFromParse() {
let query = PFQuery(className:"Your_Class_Name")
query.findObjectsInBackgroundWithBlock { (objects, error) -> Void in
if error == nil {
for object in objects! {
// Do something
}
} else {
print(error)
}
}
}

The official parse documentation explains how to make queries - there is sample code in swift.
In your case you have to use findObjectsInBackgroundWithBlock
:
var query = PFQuery(className:"EventObject")
query.findObjectsInBackgroundWithBlock { (objects: [AnyObject]!, error: NSError!) -> Void in
if error == nil {
for object in objects {
// Do something
}
} else {
println(error)
}
}
which, if successful, provides to the closure an array of objects matching the query - since there's no filter set in the query, it just returns all records.
