Firebase data into an Array of dictionaries. iOS, Swift - swift

Question

I'm trying to retrieve data from a firebase database and store the result in an array of dictionaries. I want to store the data in this way....
[[postcode: postcode, latitude: 87.28764862, longitude: -23.94679475694, registration: registration], [postcode: postcode, latitude: 87.28764862, longitude: -23.94679475694, registration: registration], [postcode: postcode, latitude: 87.28764862, longitude: -23.94679475694, registration: registration]]
The result I'm getting is...
Tony: before append post []
Tony: post [appname.Post]
Where am I going wrong?
var places = [String]()
var postsNew = [Post]()
var posts = [String: Any]()
DataService.ds.REF_POSTS.observe(.value, with: { (snapshot) in
if snapshot.hasChild("postCodes") {
let refToUser = DataService.ds.REF_POSTS
refToUser.child("postCodes").observe(.value, with: { snapshot in
let value = snapshot.value as? NSDictionary
let postsIds = value?.allKeys as! [String]
for postId in postsIds {
let refToPost = Database.database().reference(withPath: "posts/" + "postCodes/" + postId)
refToPost.observe(.value, with: { snapshot in
if snapshot.exists() {
let postDict = snapshot.value as? Dictionary<String, AnyObject>
let pCodeData = snapshot.key
let post = Post(postKey: pCodeData, postData: postDict!)
self.configureCell(post: post)
print("Tony: before append post \(self.postsNew)")
self.postsNew.append(post)
print("Tony: post \(self.postsNew)")
}else {
print("Tony: Couldn't get the data")
}
})
}
})
}else {
print("Tony: No Favs added, couldn't get the data")
}
})
func configureCell(post: Post) {
self.postData = post
self.latitude = post.latitude
self.longitude = post.longitude
self.postCodeDB = post.postCode
self.registration = post.other2
}
and in my Post class..
init(postKey: String, postData: Dictionary<String, AnyObject>) {
self._postKey = postKey
my firebase data...
If I add another one to my firebase I get this result...

I found the answer by reviewing my code.
DataService.ds.REF_POSTS.child("postCodes").observe(.value, with: { (snapshot) in
let value = snapshot.value as? NSDictionary
let postsIds = value?.allKeys as! [String]
for postId in postsIds {
let refToPost = Database.database().reference(withPath: "posts/" + "postCodes/" + postId)
refToPost.observe(.value, with: { snapshot in
if snapshot.exists() {
let postDict = snapshot.value as? [String: AnyObject]
print("Tony: before append post \(self.posts)")
self.posts.append(postDict!)
print("Tony: post \(self.posts)")
self.showSightingsOnMap()
}else {
print("Tony: Couldn't get the data")
}
})
}
})
