Retrieving object from Parse.com

Question

I'm having some struggles with the code when trying to retrieve an PFObject from Parse.

This is my code:

    var query = PFQuery(className: "message")
    query.whereKey("recipientUsername", equalTo: PFUser.currentUser())
    var messages = query.findObjects()

    var done = false

    for message in messages {

        if done == false {

            var messageObject:PFObject =


        done == true

The problem is in the "var messageObject:PFObject = ". I do not know what to write to complete this statement.

Any ideas on how to proceed would be appreciated.

Whatever you have to do with the messageObject variable, you don't need it. The findObjects method returns an array of PFObjects. Since I presume that under the hood it returns NSArray, which is translated to [AnyObject] in swift, you just have to downcast to an array of PFObject:

var messages = query.findObjects() as [PFObject]

then in your loop the message variable is automatically inferred the PFObject type, hence you don't need to create another messageObject variable:

for message in messages { // message is of PFObject type
    if done == false {
        // Do whatever you need with message
        println(message)
    }
}

Update Sep 14, 2015: as of Swift 1.2, the new as! forced conversion operator must be used:

var messages = query.findObjects() as! [PFObject]

Thanks to @Kiran Ruth R for pointing that out.
