Manage user attributes
Fetch the current user's attributes
Invoke the following api to get the list of attributes assigned to the user.
func fetchAttributes() async { do { let attributes = try await Amplify.Auth.fetchUserAttributes() print("User attributes - \(attributes)") } catch let error as AuthError{ print("Fetching user attributes failed with error \(error)") } catch { print("Unexpected error: \(error)") }}func fetchAttributes() -> AnyCancellable { Amplify.Publisher.create { try await Amplify.Auth.fetchUserAttributes() }.sink { if case let .failure(authError) = $0 { print("Fetch user attributes failed with error \(authError)") } } receiveValue: { attributes in print("User attributes - \(attributes)") }}Update user attribute
Invoke the update api for creating new or updating existing user attributes.
func updateAttribute() async { do { let updateResult = try await Amplify.Auth.update( userAttribute: AuthUserAttribute(.phoneNumber, value: "+2223334444") )
switch updateResult.nextStep { case .confirmAttributeWithCode(let deliveryDetails, let info): print("Confirm the attribute with details send to - \(deliveryDetails) \(String(describing: info))") case .done: print("Update completed") } } catch let error as AuthError { print("Update attribute failed with error \(error)") } catch { print("Unexpected error: \(error)") }}func updateAttribute() -> AnyCancellable { Amplify.Publisher.create { try await Amplify.Auth.update( userAttribute: AuthUserAttribute(.phoneNumber, value: "+2223334444") ) }.sink { if case let .failure(authError) = $0 { print("Update attribute failed with error \(authError)") } } receiveValue: { updateResult in switch updateResult.nextStep { case .confirmAttributeWithCode(let deliveryDetails, let info): print("Confirm the attribute with details send to - \(deliveryDetails) \(info)") case .done: print("Update completed") } }}Verify user attribute
Some attributes require confirmation for the attribute update to complete. If the attribute need to be confirmed, the result of the above api will be CONFIRM_ATTRIBUTE_WITH_CODE. A confirmation code will be sent to the delivery medium mentioned in the delivery details. When the user gets the confirmation code, you can present a UI to the user to enter the code and invoke the confirm attribute api with their input:
func confirmAttribute() async { do { try await Amplify.Auth.confirm(userAttribute: .email, confirmationCode: "390739") print("Attribute verified") } catch let error as AuthError { print("Update attribute failed with error \(error)") } catch { print("Unexpected error: \(error)") }}func confirmAttribute() -> AnyCancellable { Amplify.Publisher.create { try await Amplify.Auth.confirm(userAttribute: .email, confirmationCode: "390739") }.sink { if case let .failure(authError) = $0 { print("Update attribute failed with error \(authError)") } } receiveValue: { _ in print("Attribute verified") }}Send user attribute verification code
If an attribute needs to be verified while the user is authenticated, invoke the send api as shown below:
func resendCode() async { do { let deliveryDetails = try await Amplify.Auth.resendConfirmationCode(forUserAttributeKey: .email) print("Resend code send to - \(deliveryDetails)") } catch let error as AuthError { print("Resend code failed with error \(error)") } catch { print("Unexpected error: \(error)") }}func resendCode() -> AnyCancellable { Amplify.Publisher.create { try await Amplify.Auth.resendConfirmationCode(forUserAttributeKey: .email) }.sink { if case let .failure(authError) = $0 { print("Resend code failed with error \(authError)") } } receiveValue: { deliveryDetails in print("Resend code sent to - \(deliveryDetails)") }}
