AuthenticationManager를 만들어줌

import Foundation
import FirebaseAuth

struct AuthDataResultModel {
    let uid: String
    let email: String?
    let photoUrl: String?
    
    init(user: User) {
        self.uid = user.uid
        self.email = user.email
        self.photoUrl = user.photoURL?.absoluteString
    }
}

final class AuthenticationManager {
    
    static let shared = AuthenticationManager()
    private init() { }
    
    func createUser(email: String, password: String) async throws -> AuthDataResultModel {
        let authDataResult = try await Auth.auth().createUser(withEmail: email, password: password)
        
        return AuthDataResultModel(user: authDataResult.user)
    }
}

유저 로그아웃

AuthService에 logout 메소드 작성해주고

SettingsView에 signOut 메소드 만들어줌!
이때 UserDefaults로 로그인 기록 저장하고 있었으니까 signOut하면 UserDefaults도 전부 삭제하게끔 해줬다

Post To Database

// Used to handle upload and download data (other than User) from our Database
import Foundation
import SwiftUI
import FirebaseFirestore

class DataService {
    
    //MARK: - Properties
    
    static let instance = DataService()
    
    private var REF_POSTS = DB_BASE.collection("posts")
    
    //MARK: - Create Function
    
    func uploadPost(image: UIImage, caption: String?, displayName: String, userID: String, handler: @escaping (_ success: Bool) -> ()) {
        // Create new post document
        let document = REF_POSTS.document()
        let postID = document.documentID
        
        // Upload image to storage
        ImageManager.instance.uploadPostImage(postID: postID, image: image) { success in
            
            if success {
                // Successfully uploaded image data to Storage
                // Now upload post data to Database
                
                let postData: [String: Any] = [
                    DatabasePostField.postID : postID,

                    DatabasePostField.displayName : displayName,
                    DatabasePostField.caption : caption,
                    DatabasePostField.dateCreated : FieldValue.serverTimestamp()
                ]
                
                document.setData(postData) { error in
                    if let error = error {
                        print("Error uploading data to post document. \(error)")
                        handler(false)
                        return
                    } else {
                        // return back to the app
                        handler(true)
                        return
                    }
                }                
                
            } else {
                print("Error uploading post image to firebase")
                handler(false)
                return
            }
        }
    }
