Can someone help me fix my xcode.

Welcome to the forum.

Please show the complete code.

How is User defined ?

It seems you forgot a closing parenthesis, isn't it ?

Here is the complete code:

import SwiftUI import FirebaseAuth import FirebaseFirestore import FirebaseSharedSwift

struct ProfileView: View { @State private var user: User? @State private var isEditing = false @State private var profilePicture: Image? = Image(systemName: "person.circle.fill")

@State private var name: String = ""
@State private var email: String = ""
@State private var phoneNumber: String = ""
@State private var bio: String = ""


private var userId: String? {
    Auth.auth().currentUser?.uid
}

var body: some View {
    VStack {
        if let user = user {
            
            VStack {
                profilePicture?
                    .resizable()
                    .scaledToFill()
                    .frame(width: 100, height: 100)
                    .clipShape(Circle())
                    .overlay(Circle().stroke(Color.white, lineWidth: 4))
                    .shadow(radius: 10)
                    .padding()
                
                Button(action: {
                    
                    
                }) {
                    Text("Change Profile Picture")
                        .foregroundColor(.blue)
                }
                .padding(.bottom)
            }
            
            
            Form {
                Section(header: Text("Profile Information")) {
                    TextField("Name", text: $name)
                        .disabled(!isEditing)
                    TextField("Email", text: $email)
                        .disabled(true)  // Email is usually not editable
                    TextField("Phone Number", text: $phoneNumber)
                        .disabled(!isEditing)
                    TextField("Bio", text: $bio)
                        .disabled(!isEditing)
                }
                
               
                Section {
                    if isEditing {
                        Button("Save Changes") {
                            saveChanges()
                        }
                        Button("Cancel") {
                            isEditing.toggle()
                            loadUserData()
                        }
                    } else {
                        Button("Edit Profile") {
                            isEditing.toggle()
                        }
                    }
                }
            }
        } else {
           
            ProgressView("Loading profile...")
                .progressViewStyle(CircularProgressViewStyle())
        }
    }
    .onAppear {
        loadUserData()
    }
}


private func loadUserData() {
    guard let userId = userId else { return }
    
    let db = Firestore.firestore()
    db.collection("users").document(userId).getDocument { snapshot, error in
        if let error = error {
            print("Error fetching user data: \(error)")
        } else if let snapshot = snapshot, snapshot.exists {
            do {
                
                let fetchedUser = try snapshot.data(as: User.self)
                self.user = fetchedUser
                self.name = fetchedUser?.name ?? ""
                self.email = fetchedUser?.email ?? ""
                self.phoneNumber = fetchedUser?.phoneNumber ?? ""
                self.bio = fetchedUser?.bio ?? ""
            
                if let pictureURL = fetchedUser?.profilePictureURL {
                    loadProfilePicture(from: pictureURL)
                }
            } catch {
                print("Error decoding user data: \(error)")
            }
        }
    }
}



private func loadProfilePicture(from url: String) {
    guard let url = URL(string: url) else { return }
    
    Task {
        do {
            let (data, _) = try await URLSession.shared.data(from: url)
            if let uiImage = UIImage(data: data) {
                profilePicture = Image(uiImage: uiImage)
            }
        } catch {
            print("Failed to load image from URL: \(error)")
        }
    }
}


private func saveChanges() {
    guard let userId = userId else { return }
    
    let db = Firestore.firestore()
    let userRef = db.collection("users").document(userId)
    
    
    let updatedUser = User(
        coder: <#NSCoder#>,
        id: userId,
        name: name,
        email: email,
        phoneNumber: phoneNumber,
        profilePictureURL: nil,
        bio: bio
    )
    
    do {
       
        try userRef.setData(from: updatedUser) { error in
            if let error = error {
                print("Error saving user data: \(error)")
            } else {
                print("User data successfully saved!")
            }
        }
    } catch {
        print("Error serializing user data: \(error)")
    }
}

}

Here is one error.

Here is the other

I was looking for User definition. It is a Firebase class, should be this one: https://firebase.google.com/docs/reference/swift/firebaseauth/api/reference/Protocols/UserInfo.html

I suppose error is here:

    let updatedUser = User(
        coder: <#NSCoder#>,
        id: userId,
        name: name,
        email: email,
        phoneNumber: phoneNumber,
        profilePictureURL: nil,
        bio: bio
    )

why do you include coder here ? And what does <#NSCoder#> mean ? Where did you get it ?

I understand you have several init for User:

• either with coder

public required convenience init?(coder: NSCoder)

• or direct declaration with all the properties.

So, you'd better study carefully FireBaseAuth documentation.

Can someone please give me a easy way to fix this code.
