User Profile

I am, at least, per success of the operation able to store a username and password in the keychain using the "addUser" function in the code below. I then when doing a login call the "authenticateUser" function but I get a -25300 error (errSecItemNotFound). I'm close here but missing something. Any help would be appreciated. class func addUser(username: String, password: String) -> Bool { let serviceName = AppValues.appName // Replace this with a unique identifier for your app let account = username.data(using: .utf8)! let passwordData = password.data(using: .utf8)! let query: [CFString: Any] = [ kSecClass: kSecClassGenericPassword, kSecAttrService: serviceName, kSecAttrAccount: account, kSecValueData: passwordData, kSecAttrAccessible: kSecAttrAccessibleWhenUnlockedThisDeviceOnly ] // Delete any existing items with the same account before adding the new one SecItemDelete(query as CFDictionary) let status = SecItemAdd(query as CFDictionary, nil) guard status == errSecSuccess else { evaluateKeychainError(errorCode: status) return false } LogEvent.print(module: "Authentication.keychain.addUser", message: "\(username)/\(password) added successfully.") return true } class func authenticateUser(username: String, password: String) -> Bool { let usernameData = username.data(using: .utf8)! let query: [String: Any] = [ kSecClass as String: kSecClassInternetPassword, kSecAttrServer as String: AppValues.appName, // Replace with your server or app identifier kSecAttrAccount as String: usernameData, kSecReturnData as String: true, kSecMatchLimit as String: kSecMatchLimitOne ] var result: AnyObject? let status = SecItemCopyMatching(query as CFDictionary, &result) if status == errSecSuccess, let passwordData = result as? Data, let retrievedPassword = String(data: passwordData, encoding: .utf8) { LogEvent.print(module: "Authentication.keychain.authenticateUser", message: "\(username)/\(password)/\(retrievedPassword) authenticated successfully.") return retrievedPassword == password } else { LogEvent.print(module: "Authentication.keychain.authenticateUser", message: "Error \(status)") evaluateKeychainError(errorCode: status) return false } }

How do I delete all the rows in an entity and/or delete the entity all together in SwiftData? Here is a function I used to delete an entity in core data for reference. class func deleteEntity(entity: String) { let fetchRequest1: NSFetchRequest<NSFetchRequestResult> = NSFetchRequest(entityName: entity)//entity.fetchRequest() let batchDeleteRequest1 = NSBatchDeleteRequest(fetchRequest: fetchRequest1) _ = try? PersistanceController.shared.container.viewContext.execute(batchDeleteRequest1) print("Deleting coredata entity: \(entity)") }
