All I'm trying to do is fetch all the posts to the collection view that are within a certain radius of the current user. Currently I'm getting all the current users posts within the location but that is all. I can't figure out how to convert it to fetch all the posts from all the users.

FetchPostUserIds Is returning a snapshot of all the users and there UID

The geoFire query is only returning the postId from the current user. It shouldn't be I assume

Note: Updated Code

var PostKey: String?

var geoFire: GeoFire?

var regionQuery: GFRegionQuery?

var foundQuery: GFCircleQuery?

var geoFireRef: DatabaseReference!



override func viewDidLoad() {

    super.viewDidLoad()



    guard let uid = Auth.auth().currentUser?.uid else { return }

    geoFireRef = Database.database().reference().child("posts").child(uid)

    geoFire = GeoFire(firebaseRef: geoFireRef)



}



func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {



    let userLocation: CLLocation = locations[0] as CLLocation

    let currentUserLocation = userLocation



    let circleQuery = geoFire?.query(at: currentUserLocation, withRadius: 100.0)

    _ = circleQuery?.observe(.keyEntered, with: { (key, location) in

        self.PostKey = key

        self.locationManager.stopUpdatingLocation()

    })

}



 fileprivate func fetchPostsWithUser(user: User) {



    guard let key = PostKey else { return }



    let ref = Database.database().reference().child("posts").child(user.uid).child(key)

    ref.observeSingleEvent(of: .value, with: { (snapshot) in

        self.collectionView?.refreshControl?.endRefreshing()



        guard let dictionary = snapshot.value as? [String: Any] else { return }



        var post = Post(user: user, dictionary: dictionary)

        post.id = key



        self.posts.append(post)

        self.posts.sort(by: { (post1, post2) -> Bool in

            return post1.creationDate.compare(post2.creationDate) == .orderedDescending

        })

        self.collectionView?.reloadData()

    }) { (error) in

        print(error)

    }



}



fileprivate func fetchPostUserIds() {



    let ref = Database.database().reference().child("users")

    ref.observeSingleEvent(of: .value, with: { (snapshot) in



        guard let userIdKey = snapshot.value as? [String: Any] else { return }



        userIdKey.forEach({ (key, value) in

            Database.fetchUserWithUID(uid: key, completion: { (user) in

                self.fetchPostsWithUser(user: user)

            })

        })



    }) { (error) in

        print(error)

    }



}

Try to debug and look what you got in the snapshot in your function, and also what fetchUserWithUID return

fileprivate func fetchPostUserIds() {



     let ref = Database.database().reference().child("users")

        ref.observeSingleEvent(of: .value, with: { (snapshot) in



            guard let userIdKey = snapshot.value as? [String: Any] else { return }



            userIdKey.forEach({ (key, value) in

            Database.fetchUserWithUID(uid: key, completion: { (user) in

                self.fetchPostsWithUser(user: user)

            })

        })



    }) { (error) in

        print(error)

    }



}

Maybe with some more information I can help you

You pass paremeter user: User to method fetchPostsWithUser, but you always use the current user

guard let uid = Auth.auth().currentUser?.uid else { return }

also note these

let ref = Database.database().reference().child("users")

ref.observe(.value, with: { (snapshot) in

will load every change so think about singleObserve
