Tableview Updating wrong cell - swift

Question

I made a like button problem is when the like button is tapped the values update only the first tableview cell even if I clicked the second cell it will update the values of likes in the first tableview cell. The values update properly on firestore for each individual cell but its being loaded wrong
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
motivationThoughts.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "DailyThoughtCELL", for: indexPath) as? dailyMotivationTableViewCell
cell!.generateCellsforDailymotivation(_MotivationdataMODEL: self.motivationThoughts[indexPath.row], objectID: self.motivationThoughts[indexPath.row].motiveID)
//cell!.postID = self.motivationThoughts[indexPath.row].motiveID //this works and updates the value
//cell!.generateLikeCell(objectID: self.motivationThoughts[indexPath.row].motiveID)
return cell!
}
func loaddailymotivation() {
FirebaseReferece(.MotivationDAILY).addSnapshotListener { querySnapshot, error in
guard let snapshot = querySnapshot else {
print("Error fetching snapshots: \(error!)")
return
}
snapshot.documentChanges.forEach { diff in
if (diff.type == .added) { // this line means if the chage that happened in the document was equal to added something
let data = diff.document.data()
print("we have\(snapshot.documents.count) documents in this array")
let dailyMotivationID = data["objectID"] as! String
let dailymotivationTitle = data["Motivation title"] as! String //calls the data thats heald inside of motivation title in firebase
let dailyMotivationScripture = data["daily motivation scripture"] as! String //calls the data thats heald inside of Motivation script in firebase
let dailyMotivationNumberOfLikes = data["Number of likes in daily motivation post"]as! Int
let MdataModel = motivationDailyModel(RealMotivationID: dailyMotivationID, RealmotivationTitle: dailymotivationTitle, RealmotivationScrip: dailyMotivationScripture, RealmotivationNumberOfLikes: dailyMotivationNumberOfLikes)
self.motivationThoughts.append(MdataModel)
}
/*
I thinkyou need a method that identifies the item that needs to be modified in the array, and replace/modify it. If you add a new object, you have one more element in your table*/
if (diff.type == .modified) {
print("Modified data: \(diff.document.data())")
let newdata = diff.document.data()
let objectID = newdata["objectID"] as! String // we get the object id of the uodated item
//self.GrabThatDamnstring(grabIt: objectID)
//self.incrementLikes(NewobjectID: objectID) //write a function to grab the string from the certain post and then send it to dailymotivationviewcell into the function increment likes so so it can update the specific objectID
guard let dailymotivationIndex = self.motivationThoughts.firstIndex(where: {_ in objectID == objectID}) else { return }
var dailymotivation = self.motivationThoughts[dailymotivationIndex]
let dailyMotivationNumberOfLikes = newdata["Number of likes in daily motivation post"] as! Int
dailymotivation.motivationNumberOfLikes = dailyMotivationNumberOfLikes
self.motivationThoughts[dailymotivationIndex] = dailymotivation
// here you will receive if any change happens in your data add it to your array as you want
}
DispatchQueue.main.async {
self.tableview.reloadData()
}
}
}
}
this is the uitableview cellcode

hud.show(in: self.contentView)

//no user login so pull up login view
}
//MARK: TODO when this button is tapped ALSO WANT TO STORE THIS SNAPSHOT INTO AN ARRAY THAT WE WILL SHOW IN OUR SAVED VIEW CONTROLLEr
}
//call this function from motivation daily viewcontroller and it will also have the item that was tapped
func incrementLikes(){
//MARK: WE NEED TO FIND OUT HOW WE GET THE UUID FOR THE CERTAIN POS
FirebaseReferece(.MotivationDAILY).document(postID).updateData(["Number of likes in daily motivation post":FieldValue.increment(Int64(1))]) { (error) in
if error != nil {
print(error!.localizedDescription)
} else {
print("successfully incremented data!")
}
}
}
func changeLikeButtonMode(){
// so if likedbutton is tapped and the heart isnt red that means that the tag is = 0 so its gnna show the red heard and then also change the tag to 1 but when it is tapped again its going to change the tag to 0 and removed the red heart
if likeSavedButton.tag == 0 //means its empty
{
incrementLikes()
self.likedbuttonFIlled.isHidden = false
likeSavedButton.tag = 1
}else {

Answer 1

The condition in your guard statement always evaluates to true
guard let dailymotivationIndex = self.motivationThoughts.firstIndex(where: {_ in objectID == objectID}) else { return }
Try this instead
guard let dailymotivationIndex = self.motivationThoughts.firstIndex(where: { $0.RealMotivationID == objectID}) else { return }
