Remove value when listing firebase child node on tableViewCell - ios

Question

I am trying to list all the users from a firebase node in a table view (this is working) but would then like to remove the current user from the list (this is not working).
I've tried to use removeValue() but it still ran with the current user on the table view - also I don't want to remove the user from firebase
I then tried to make it run only if the the user autoId is not equal to the current users Id but it still shows up on the table view cell
Would appreciate any help :)
My firebase structure is like this:
"users" : {
"8x1SGi2P0KVOKm4i60JQLP1bdU63" : {
"fullname" : "bbbb",
"profileImageUrl" : "https://firebasestorage.googleapis.com/v0/b/pinion-4896b.appspot.com/o/profile_image%2F8x1SGi2P0KVOKm4i60JQLP1bdU63?alt=media&token=7932b14f-c2d8-46fd-9dd1-c607217fe8d3",
},
"B7rwHiCTlphZjKXfPSEzkIwl8RH2" : {
"fullname" : "Aaaa ",
"profileImageUrl" : "https://firebasestorage.googleapis.com/v0/b/pinion-4896b.appspot.com/o/profile_image%2FB7rwHiCTlphZjKXfPSEzkIwl8RH2?alt=media&token=072e1f41-935e-430d-af99-dc640381f8e6",
},
"FRuuk20CHrhNlYIBmgN4TTz3Cxn1" : {
"fullname" : "eeee",
"profileImageUrl" : "https://firebasestorage.googleapis.com/v0/b/pinion-4896b.appspot.com/o/profile_image%2FFRuuk20CHrhNlYIBmgN4TTz3Cxn1?alt=media&token=bf89b903-a51a-4d6d-bdef-fe2667d78842",
},
Code to which lists users:
func observeUsers(completion: #escaping (UserModel) -> Void) {
REF_USERS.observeSingleEvent(of: .childAdded, with: { snapshot in
if let dict = snapshot.value as? [String: Any] {
let user = UserModel.transformUser(dict: dict, key: snapshot.key)
//line below used first to remove value from listing on table view
//Api.User.REF_USERS.child("users").child(Api.User.CURRENT_USER!.uid).removeValue()
//line below - if user autoID is not equal to the current user then list
if user.id != Api.User.CURRENT_USER?.uid {
completion(user)
}
}
})
}
EDIT:
func loadUsers() {
var allUsers = [String]()
Api.User.REF_USERS.observe(.value, with: { snapshot in
for child in snapshot.children { //build the array of keys
let snap = child as! DataSnapshot
let key = snap.key
allUsers.append(key)
print(allUsers)
}
})
}

Answer 1

instead of removing try this
create model of your tabledata
then create an empty array of it
while fetching the data append all except that which has same currentuser.uid
then reload the tableview this will show all the data except the current user
this is the code as promised:
but this need a little modification in your database
make your database like this
"users":{
"childbyautid":{
"fullname": "name",
"profileimageurl": "your url",
"userid": "userid"
}
then you can write like this
var myArr = [String]()
Database.database().reference.child("users").observe(.value){(snapshot) in
if snapshot.childcount > 1 { self.myArr.removeAll()
for data in snapshot.children.allObjects as! [DataSnapshot]{
if let d = data.value as? [string: any]{
if Auth.auth.currentuser.uid != d["userid"]{
myArr.append(d["name"]}else{print("this is the user itself"}}}

Answer 2

You can control this in you loadUsers by adding userId check like below
func loadUsers() {
var allUsers = [String]()
Api.User.REF_USERS.observe(.value, with: { snapshot in
for child in snapshot.children { //build the array of keys
let snap = child as! DataSnapshot
let key = snap.key
if key != currentUser.id{
allUsers.append(key)
}
print(allUsers)
}
})
}
