Swift Firestore using an Array to get document fields - arrays

Question

I am using an array named PosterEmail to search for a document field name "First Name" in my Firestore Database.
Here you can see my database set up.
FirebaseSetup
enter image description here
As you can see my Database is Public then in the document I have the user's email as the document name and in that document I have their information such as their first name, last name, and profile photo url.
I search for the document id using an Array
The PosterEmail array is
PosterEmail = ["chainsawloco#yahoo.com", "allmight#gmail.com", "allmight#gmail.com", "chainsawloco#yahoo.com"]
I am going through my PosterEmail index by setting a variable "profilecount" to 0 and adding 1 to it everytime to go through the PosterArray
let docRef = db.collection("Public").document("\(self.PosterEmail[self.profilecount])")
But it seems that the code above never searches for the Firebase document named after the second item in my Array
The result is just
["Irving ", "Irving ", "Irving ", "Irving "]
The result should end up as [Irving, Allmight, Allmight, Irving]
Is there something I"m doing wrong?
Below is where I call my getPosteInformation() in another method called getDatFromFirestore() (ehhh I know my method name has a typo but I can fix that later)
if let postedBy = document.get("postedBy") as? String {
print("Postby = document.get(postedby = \(postedBy)")
self.PosterEmail.append(postedBy)
if self.PosterEmail.count > 0 {
self.getPosteInformation()
}
}
}
}
}
Below you can see my full code.
func getDatFromFirestore() {
let firestoreDatabase = Firestore.firestore()
firestoreDatabase.collection("Posts").order(by: "Date" , descending : true).getDocuments { (snapshot, error) in
if error != nil {
print(error?.localizedDescription ?? "Connection Error")
} else {
self.userPostImageArray.removeAll(keepingCapacity: false)
self.userCommentArray.removeAll(keepingCapacity: false)
self.userCommentArray.removeAll(keepingCapacity: false)
self.likeArray.removeAll(keepingCapacity: false)
self.PosterEmail.removeAll(keepingCapacity: false)
self.userProfilePhotoArray.removeAll(keepingCapacity: false)
self.PosterFirstNameArray.removeAll(keepingCapacity: false)
self.PosterLastNameArray.removeAll(keepingCapacity: false)
for document in snapshot!.documents {
let documentID = document.documentID
self.documentIDArray.append(documentID)
if let postDescription = document.get("PostDescription") as? String {
self.userPostDescription.append(postDescription)
}
if let imageUrl = document.get("imageUrl") as? String {
self.userPostImageArray.append(imageUrl)
}
if let PostLikes = document.get("Likes") as? Int {
self.likeArray.append(PostLikes)
}
if let postTimeStamp = document.get("Date") as? Timestamp {
let date = postTimeStamp.dateValue()
let formatter = DateFormatter()
formatter.dateFormat = "HH:mm MM/dd/yyyy"
let dateString = formatter.string(from: date)
let timeStampAsString = dateString
self.postDate.append(timeStampAsString)
}
if let postedBy = document.get("postedBy") as? String {
print("Postby = document.get(postedby = \(postedBy)")
self.PosterEmail.append(postedBy)
if self.PosterEmail.count > 0 {
self.getPosteInformation()
}
}
}
}
}
self.VidaFeed.reloadData()
}
func getPosteInformation() {
print("")
print(PosterEmail[profilecount])
print(profilecount)
print("")
print(PosterEmail)
let docRef = db.collection("Public").document("\(self.PosterEmail[self.profilecount])")
docRef.getDocument { (document, error) in
if let document = document, document.exists {
let dataDescription = document.data().map(String.init(describing:)) ?? "nil"
print("Document data: \(dataDescription)")
if self.profilecount < self.PosterEmail.count {
if let PosterFirstName = document.get("First Name") as? String {
self.PosterFirstNameArray.append(PosterFirstName)
print(self.PosterFirstNameArray)
print("\(self.profilecount)")
if self.PosterEmail.count > self.profilecount {
self.profilecount = self.profilecount + 1
}
}
}
} else {
print("Document does not exist")
}
}
}

if let postedBy = document.get("postedBy") as? String {
print("Postby = document.get(postedby = \(postedBy)")
self.PosterEmail.append(postedBy)
self.PosterFirstNameArray.append("")
if self.PosterEmail.count > 0 {
self.getPosteInformation(profCount: self.profileCount)
}
if self.PosterEmail.count > self.profilecount {
self.profilecount = self.profilecount + 1
}
}
And now if you could modify this method like this:
func getPosteInformation(profCount:Int) {
//and inside the async call back instead of the following try
/*if let PosterFirstName = document.get("First Name") as? String {
self.PosterFirstNameArray.append(PosterFirstName)
print(self.PosterFirstNameArray)
print("\(self.profilecount)")
if self.PosterEmail.count > self.profilecount {
self.profilecount = self.profilecount + 1
}
}*/
if let PosterFirstName = document.get("First Name") as? String {
self.PosterFirstNameArray[profCount] = PosterFirstName
print(self.PosterFirstNameArray)
print("\(profCount)")
}
}
