Problem is on iPhone 4s and 5 I can't fetch data's.But in other devices its works.Also I can make login process and some other queries too. Also that's not giving me an error.

This is my code

let query = PFQuery(className: "Activity")
        query.orderByDescending("createdAt")
        query.whereKey("members", equalTo: PFUser.currentUser()!)
        query.whereKey("fromUser", notEqualTo: PFUser.currentUser()!)
        query.includeKey("fromUser")
        query.includeKey("members")
        query.whereKey("Type", notEqualTo: "joinToBons")
        query.includeKey("friends_request")
        query.includeKey("group")
        self.label = UILabel(frame: CGRectMake(0, self.tableView.frame.size.height / 2, self.view.frame.size.width, 20))

        query.findObjectsInBackgroundWithBlock { (object, error) in
            self.label.removeFromSuperview()
            if error == nil {
                self.notifications = object!
                if object?.count == 0 {
                    self.dataAvailable = false
                    self.label.center = self.tableView.center
                    self.label.textAlignment = .Center
                    self.label.text = "nonotification".localized()
                    self.notifications.removeAll()
                    self.view.addSubview(self.label)

                }else {
                    self.label.performSelectorOnMainThread(#selector(self.label.removeFromSuperview), withObject: nil, waitUntilDone: false)
                    self.label.removeFromSuperview()
                    self.label.hidden = true
                    self.label.text = ""
                    self.dataAvailable = true
                }
            }else {
                print(error)
            }
            self.view.setNeedsLayout()
            self.loader.hideActivityIndicatorWithAnimation(self.view)
            self.tableView.reloadData()
            self.refreshControl?.endRefreshing()
        }

Hi @mkaya93 do you get any logs in xcode? I don't see any reason why it will not work on iPhone 4/5 but on other devices it will work.

I'm experiencing the same problem. Did you figure out why this was happening?

[flovilmart]

HTTPS issue? HTTP issue? ATS?

[bhirshman1]

Thank you for the quick response!

I have an app created in Swift running on parse server hosted by Heroku. When the app runs on iPhone 5s or newer (in the Xcode simulator and in real life), a query finds objects. Only on the iPhone 5 does the same query not find objects. Is there any reason for this that you can think of? The iOS versions are the same in each case.

[flovilmart]

Can you use the request interceptor? Probably that may help.

Are the queries received on the server? You can turn on verbose logging with setting the VERBOSE=1 env. variable

Hi @bhirshman1,

I was just changed query and its worked properly. But I'm not remembering which parts I changed on query.

[bhirshman1]

Interesting...

You recall experiencing the same thing I am though? Your query yielded no objects when using an iPhone 5, yet found objects when using a 5s, 6, etc.? Quite honestly we might be the only 2 people ever to experience this, considering I can't find anything else on the internet mentioning it.

So it turns out that iPhone 5s and newer are 64-bit devices, as opposed to 32-bit for iPhone 5 and older. 32-bit devices can't successfully query when a key is an array. My explanation I'm sure isn't the most technically sophisticated. It's explained better in the below links. Seems the only solution at the moment is a work around on the server side, which i'm hesitant to do.
