Firebase #DocumentID property wrapper not working - ios

Question

I'm trying to update certain values in a specific Firebase document, however, whenever the code fires, I get the error:
[FirebaseFirestore][I-FST000001] WriteStream (7fc6c510be38) Stream error: 'Not found: No document to update: projects/htg-inspection/databases/(default)/documents/Projects/365A2F53-CB38-47A6-93C3-7D6DA14038D9
Based on the response it would seem that the Id I get back from my data struct is different from the document ID that I'm trying to update. I assumed that the #DocumentID property wrapper is supposed to solve this, or am I doing/not doing something correctly/incorrectly?
These are the corresponding DocumentIDs and what I'm getting back are some random strings (assumingly from the Swift's UUID initializer)
My Projects Data Struct:
import Foundation
import FirebaseFirestoreSwift
import FirebaseFirestore
import Firebase
struct ProjectsData: Identifiable, Codable{
#DocumentID var id: String? = UUID().uuidString
var title: String
var client: String
var description: String
var inspections: [InspectionsData]
enum CodingKeys: String, CodingKey{
case id
case title
case client
case description
case inspections
}
}
Sub-Collection:
struct InspectionsData: Identifiable, Codable {
var id = UUID()
var category: Category
var trade: String
var inspectionDate: Date
var dueDate: Date
var assigned: Bool
var location: String
var images: [InspectionImages]
var checklists: [ChecklistsData]
var dateToString: String{
let formatter = DateFormatter()
formatter.dateFormat = "MMMM dd, YYYY "
return formatter.string(from: inspectionDate)
}
var dueDateToString: String{
let formatter = DateFormatter()
formatter.dateFormat = "MMMM dd, YYYY "
return formatter.string(from: dueDate)
}
}
struct ChecklistsData: Identifiable, Codable{
var id = UUID()
var question: String
var hasPassed: Bool
var hasFailed: Bool
var isnotApplicable: Bool
}
enum ChecklistCodingKeys: String, CodingKey{
case id
case question
case hasPassed
case hasFailed
case isnotApplicable
}
My View Model:
class ProjectsViewModel: ObservableObject {
#Published var projects = [ProjectsData]()
#Published var inspectionData = [InspectionsData]()
#Published var assignedProjects: [AssignedProjectsModel] = []
#Published var retrievePhotos = [UIImage]()
#Published var inspectionImages = [InspectionImages]()
#Published var showImageViewer = false
#Published var selectedImageID: String = ""
#Published var checklists = [ChecklistsData]()
#Published var hasPassed = false
#Published var hasFailed = false
#Published var isnotApplicable = false
func updateChecklist(_ checklist: ProjectsData, hasPassed: Bool, hasFailed: Bool, isnotApplicable: Bool) {
if let documentId = checklist.id {
db.collection("Projects").document(documentId).updateData(["checklists" : ["hasPassed" : hasPassed, "hasFailed" : hasFailed, "isnotApplicable" : isnotApplicable]]) {
error in
if let error = error {
print(error.localizedDescription)
} else {
print("Document has been updated")
}
}
}
}
}
The View that I'm trying to update the database from:
struct ChecklistComponent: View {
#State var hasPassed: Bool
#State var hasFailed: Bool
#State var isnotApplicable: Bool
#ObservedObject var checklistvm = ProjectsViewModel()
var documentID: ProjectsData
var checklistItem: String = ""
var question: String = ""
var body: some View {
VStack{
HeaderOne(text: question, size: 16)
Spacer()
HStack{
ChecklistButton(text: "Pass", textColor: hasPassed ? "#00AA97" : "#696969", buttonColor: hasPassed ? "#B0EFE8" : "#DBDBDB",
action: {
hasPassed.toggle()
hasFailed = false
isnotApplicable = false
checklistvm.updateChecklist(documentID, hasPassed: hasPassed, hasFailed: hasFailed, isnotApplicable: isnotApplicable)
})
ChecklistButton(text: "Fail", textColor: hasFailed ? "#AA0000" : "#696969", buttonColor: hasFailed ? "#EFB0B0" : "#DBDBDB",
action: {
hasFailed.toggle()
hasPassed = false
isnotApplicable = false
checklistvm.updateChecklist(documentID, hasPassed: hasPassed, hasFailed: hasFailed, isnotApplicable: isnotApplicable)
})
ChecklistButton(text: "N/A", textColor: isnotApplicable ? "#89AA00" : "#696969", buttonColor: isnotApplicable ? "#EDEFB0" : "#DBDBDB",
action: {
isnotApplicable.toggle()
hasFailed = false
hasPassed = false
checklistvm.updateChecklist(documentID, hasPassed: hasPassed, hasFailed: hasFailed, isnotApplicable: isnotApplicable)
})
}
}
.padding()
.frame(width: UIScreen.main.bounds.width-30 ,height: 161)
.background(.white)
.cornerRadius(31)
}
}
Of course this is a lot of code and I can't share the entire project, but hopefully this can give enough context to lend your assistance.
Using #FirestoreQuery wrapper:
import SwiftUI
import Firebase
import FirebaseFirestore
import FirebaseFirestoreSwift
struct HomeView: View {
#State var searchable = ""
#State var navtoView = false
#State var showLogoutdialog = false
#ObservedObject var homevm = HomeViewModel()
var auth = AuthService()
#Environment(\.presentationMode) var presentationmode
#State var firstname = ""
#ObservedObject var projectvm = ProjectsViewModel()
#State var selectedProject: ProjectsData?
#FirestoreQuery(collectionPath: "Projects") var projects: [ProjectsData]
var body: some View {
NavigationView{
ScrollView(.vertical){
Spacer()
.height(70)
HeaderComponent(firstname: users.firstName)
SearchBar(searchText: $searchable)
.padding(.bottom)
VStack {
ForEach(projects, id: \.id) { item in
ProjectFeedCard(projectTitle: item.title, client: item.client)
.onTapGesture {
self.selectedProject = item
navtoView.toggle()
}
}
}
//MARK: NavigationLinks
NavigationLink(destination:ProjectView(inspections: selectedProject?.inspections ?? [], projectTitle: selectedProject?.title ?? "" , client: selectedProject?.client ?? "",description: selectedProject?.description ?? "", documentID: selectedProject ?? ProjectsData(title: "", client: "", description: "", inspections: []), checklists: []) , isActive: $navtoView){
EmptyView()
}
Spacer()
CustomButton(action: {showLogoutdialog.toggle()}, buttonText: "Log Out", buttonColor: .accentColor)
.padding()
.confirmationDialog("Are you sure?", isPresented: $showLogoutdialog, titleVisibility: .visible){
Button("Sign Out", role: .destructive){
homevm.logOutApp()
presentationmode.wrappedValue.dismiss()
}
}
.onAppear{
projectvm.fetchProjects()
}
}
.background(Color(hexadecimal: "#F8F8F8"))
.ignoresSafeArea()
.navigationBarHidden(true)
}
}
}

I managed to solve the issue by changing the id variable to a String and re-did the fetch projects function. So in short I just completely scrapped the #DocumentID wrapper which didn't seem to work. The #FirestoreQuery query wrapper worked after I changed the ID variable in my data model, but I didn't need it again since my View Model did the job
Data Struct:
struct ProjectsData: Identifiable, Codable{
var id: String
var title: String?
var client: String?
var description: String?
var inspections: [InspectionsData]
enum CodingKeys: String, CodingKey{
case id
case title
case client
case description
case inspections
}
}
I refactored the function that gets documents from Firestore to this:
func fetchFireStoreData() {
db.collection("Projects").getDocuments { snapshot, error in
if error == nil {
if let snapshot = snapshot{
//Get all documents
self.projects = snapshot.documents.map({ document in
let id = document.documentID
let title = document["title"] as? String ?? ""
let client = document["client"] as? String ?? ""
let description = document["description"] as? String ?? ""
let inspections = document["inspections"] as? [String : [String : Any]]
var inspectionsArray = [InspectionsData]()
if let inspections = inspections {
for inspection in inspections {
let categoryText = inspection.value["category"] as? String ?? "error"
let category = Category(rawValue: categoryText) ?? .Electrical
let trade = inspection.value["trade"] as? String ?? "error"
let inspectionDate = (inspection.value["inspectionDate"] as? Timestamp)?.dateValue() ?? Date()
let dueDate = inspection.value["dueDate"] as? Date
let assigned = inspection.value["assigned"] as? Bool ?? false
let location = inspection.value["inspection"] as? String ?? ""
let images = inspection.value["images"] as? [String : [String : Any]]
let checklists = inspection.value["checklists"] as? [String : [String : Any]]
var imagesArray = [InspectionImages]()
var checklistsArray = [ChecklistsData]()
if let checklists = checklists{
for list in checklists {
let question = list.value["question"] as? String ?? "error"
let hasPassed = list.value["hasPassed"] as? Bool ?? false
let hasFailed = list.value["hasFailed"] as? Bool ?? false
let isnotApplicable = list.value["isnotApplicable"] as? Bool ?? false
checklistsArray.append(ChecklistsData(question: question, hasPassed: hasPassed, hasFailed: hasFailed, isnotApplicable: isnotApplicable))
}
}
inspectionsArray.append(InspectionsData(category: category, trade: trade, inspectionDate: inspectionDate , dueDate: dueDate ?? Date.now, assigned: assigned, location: location, images: imagesArray, checklists: checklistsArray))
if let images = images {
for image in images {
let url = image.value["url"] as? String ?? "error"
imagesArray.append(InspectionImages(url: url))
}
}
}
}
self.projects.append(ProjectsData(id: id ,title: title, client: client, description: description, inspections: inspectionsArray))
return ProjectsData(id: id, title: title, client: client, description: description, inspections: inspectionsArray )
})
}
}
}
}
I'm now able to get the correct Document ID and now I can use my updateChecklist function.
