Swift Delete multiple objects at once Parse server

I query to the server following 

let query = PFQuery(className: "posts")
            query.whereKey("uuid", equalTo: Ncell.uuidLbl.text!)
            query.findObjectsInBackground { (objects:[PFObject]?, error:Error?) in
                if error == nil {
                    for object in objects! {
                        object.deleteInBackground(block: { (success:Bool, error:Error?) in
                            if success{

                            }
                        })
                    }
                }
            }

Rather than using a loop and deleting each object individually, I want to know if it would be possible to delete all the found objects at once to save on requests.

Yes in the Parse iOS SDK to delete multiple objects in background at once on Parse server, you can use deleteAllInBackground

You can use it with 2 different ways:

PFObject.deleteAll(inBackground: [PFObject]?)
PFObject.deleteAll(inBackground: [PFObject]?, block: PFBooleanResultBlock?)

For example: 

let query = PFQuery(className: "posts")
query.whereKey("uuid", equalTo: Ncell.uuidLbl.text!)
query.findObjectsInBackground { (objects:[PFObject]?, error:Error?) in
    if error == nil {
        PFObject.deleteAll(inBackground: objects, block: { (success:Bool, error:Error?) in
                if success {

                }
            })
        }
    }

I hope my answer was helpful 😊
