Mixing
Fetch posts by postId from firebase with swift 4
4
All I'm trying to achieve is to have the posts inside my radius append to the collection view. Currently I'm getting all the postId when the user enters the radius but nothing is being append to the collection view and I can't figure out why. Any help is very much appreciated.
var posts = [Post]()
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
guard let user = self.user else { return }
let ref = Database.database().reference().child("posts").child(key)
ref.observeSingleEvent(of: .value, with: { (snapshot) in
guard let dictionaries = snapshot.value as? [String: Any] else { return }
var post = Post(user: user, dictionary: dictionaries)
post.id = key
self.posts.append(post)
self.posts.sort(by: { (post1, post2) -> Bool in
return post1.creationDate.compare(post2.creationDate) == .orderedDescending
})
}, withCancel: { (error) in
print("There was an error getting the posts:", error)
})
})
}
fileprivate func fetchPostUserIds() {
Database.database().reference().child("users").observe(.value, with: { (snapshot) in
guard let userIdsDictionary = snapshot.value as? [String: Any] else { return }
userIdsDictionary.forEach({ (key, value) in
let uidKey = key
self.geoFireRef = Database.database().reference().child("posts").child(uidKey)
self.geoFire = GeoFire(firebaseRef: self.geoFireRef)
})
}) { (err) in
print("Failed to get user Id", err)
}
}

If you runt the code in a debugger, is theself.posts.append(post)being reached? If so, you're probably just forgetting to notify the view that it needs to repaint itself. Typically his would be something liketableView.reloadData().

self.posts.append(post)isn't being executed. Do you think I might be accessing my database wrong? @FrankvanPuffelen

Nov 20 '18 at 1:56
That sounds unexpected. Is that even the case when you put a breakpoint on it? Also, does theprint("There was an error getting the posts:", error)get executed?

Noprint("There was an error getting the posts:", error)is not getting executed. When i placed a break point onself.posts.append(post)it didn't get reached. I have no idea why. @FrankvanPuffelen

OK. So if you put a breakpoint onlet ref = Database.database().reference().child("posts").child(key)does that get hit. Note that at this point it's probably more efficient if you set a breakpoint on each line of your code, check where it gets, what the values of the various variables are, and then report all back in one go.
