"Flag" / Report user functionality to work — Swift / Xcode / Firebase - swift

Question

I'm trying to allow a user to report a user (in a Tinder-like app). To report, this button takes the user to a new VC to elaborate the issue as an email.
What I'm missing:
How can I add the reporter's and reportee's Firebase unique ID to the email (or whatever form of communication)? (So then I can investigate and take action as needed)
Here's what I have:
The code to properly send an email...
func configureMailController() -> MFMailComposeViewController {
let mailComposerVC = MFMailComposeViewController()
mailComposerVC.mailComposeDelegate = self
mailComposerVC.setToRecipients(["RadiusAppHelp#gmail.com"])
mailComposerVC.setSubject("Reporting user")
mailComposerVC.setMessageBody("Please include as much detail as possible:", isHTML: false)
return mailComposerVC
}
func showMailError() {
let sendMailErrorAlert = showAlert(withTitle: "Could not send message", message: "Please try again")
let dismiss = UIAlertAction(title: "Okay", style: .default, handler: nil)
// sendMailErrorAlert.addAction(dismiss)
// self.present(sendMailErrorAlert, animated: true, completion: nil)
}
func mailComposeController(_ controller: MFMailComposeViewController, didFinishWith result: MFMailComposeResult, error: Error?) {
controller.dismiss(animated: true, completion: nil)
}
}
The code to pull the other user's ID in the swipe view VC...
var otherUsersId = ""
var currentlyViewedUserId: String?
firebaseServer.fetchUsers {[weak self] (usersDict) in
self?.usersDict = usersDict
let fetchedUsers = Array(usersDict.values)
self?.filterBlockedUsers(from: fetchedUsers)
self?.loadFirstUser()
self?.cardView.reloadData()
}
func loadFirstUser() {
if users.count > 0 {
let imageView = UIImageView()
let storage = Storage.storage()
let storageRef = storage.reference(withPath:
"\(users[0].userId!)/photos/\(0)")
currentlyViewedUserId = users[0].userId
PhotoUploader.downloadImageUrl(from:
storageRef) { (url) in
guard let url = url else { return }
imageView.downloaded(from: url,
contentMode: .scaleAspectFill)
}
nameLbl.text = users[0].firstName
setupDetailsFor(user: users[0])
infoCollectionView.reloadData()
}
}
As well as the code to block a user (but blocking / reporting functions work independently).
Any help is greatly appreciated!

Okay, I found at least a temporary fix...
(Not using Firestore however, which I'll eventually need to implement — https://www.youtube.com/watch?v=Ofux_4c94FI)
In FirebaseFunctions.swift...
// Report Someone
func reportSomeone(with userId: String, completion:
#escaping (Error?) -> Void) {
let usersRef = db.child("users")
if let uid = Auth.auth().currentUser?.uid {
usersRef.child("\(uid)/report/\ .
(userId)").setValue(true) { (error, dbref) in
completion(error)
}
}
}
// Set Preferences for Reporting
func reportPreferences(with userId: String,
completion: #escaping (Error?) -> Void) {
let usersRef = db.child("users")
if let uid = Auth.auth().currentUser?.uid {
usersRef.child("\(uid)/preferences/\ .
(userId)").setValue(true) { (error, dbref) in
completion(error)
}
}
}
In User.swift...
var report: [String: Bool]? = [:]
func makeDictionary() -> [String: Any] {
print("")
return [
"report": report ?? [:]
]
static func makeObjectFrom(_ dictionary: [String:
Any]) -> LocalUser {
let report = dictionary["report"] as?
[String:Bool] ?? [:]
}
let localUser = LocalUser(report: report)
In the View Controller...
import Firebase
var currentUserId = Auth.auth().currentUser?.uid
var otherUsersId = ""
// Report Button
var isCurrentUserReported = false
var isOtherUserReported = false
var currentlyViewedUserId: String?
// FILTER REPORTED USERS
func filterReportUsers(from users: [LocalUser]) {
var notReportUsers = users
var notReportUsersDict = self.usersDict
var reportUsers = newUser.report ?? [:]
if let currentUserId =
Auth.auth().currentUser?.uid {
reportUsers[currentUserId] = true
}
for (userId, report) in reportUsers ?? [:] {
print("UserId...", userId)
print("UserHere...", usersDict[userId])
if let user = usersDict[userId] {
notReportUsersDict.removeValue(forKey:
userId)
}
}
let notReport = Array(notReportUsersDict.values)
self.users = notReport
}
This isn't perfect, but it works!
