Learning AWS AppSync with Amplify, AWS CLI, IOS and Swift

Set up the backend with amplify by selecting a profile, creating an amplify admin user, and granting cloud formation permissions, then initialize the cloud project and troubleshoot permission errors.

learn to integrate back-end services, enable user authentication with Amazon Cognito federated identities, and support Google or Facebook sign-in while preparing data storage in the database and S3.

Learn how user pools and identity pools work in AWS AppSync with Amplify, covering signup, login, federated logins with Facebook or Google, and identity IDs for authentication.

Implement a user authentication flow with sign in and sign up, manage user state, and conditionally show sign-in or sign-out UI, including password policies and email verification.

Learn how to implement real-time data updates with a GraphQL API using AWS AppSync and Amplify, including user sign-up and sign-in flows and subscribing to live database changes.

Compare rest and graph ql by highlighting a single endpoint, declarative queries, and strongly typed schemas; show field selection, status codes, and query-driven data retrieval.

Publish your dynamo db schema to the cloud with the amplify framework, configure a GraphQL API, and push resources, generating code and resolving permission issues.

Integrate AWS AppSync with a Swift app by initializing the AppSync client in the app delegate and performing a GraphQL mutation to create users in DynamoDB.

Power pagination with AWS AppSync by querying users with a limit, using the next token to fetch subsequent pages, and display results page by page.

Learn how to replace the top-in sign-in screen with a custom user sign-in UI, including username and password fields, and plan a new design in the next lesson.

Learn to design a signup screen using a static table view, adding text fields for username, email, and password, and a sign up button with proper constraints and navigation.

Learn to set up a backend with AWS AppSync and Amplify, initialize the app with the client, and implement a service to create a question via a mutation.

Configure an AppSync client with Cognito user pools to authenticate requests and create questions in a Swift iOS app, using Amplify and the AWS CLI with DynamoDB.

Design a quiz app view by building a storyboard-based UI with a simple view controller, navigation setup, and a stack of question and answer labels and buttons for user interaction.

Load quiz questions by running the list quiz questions query, fetch questions and answers, and display the first question in the quiz view, noting query versus mutation and cache policy.

Finalizing the quiz app by refactoring into reusable functions, adding a show message helper, loading answers on demand, and enabling navigation to the next question with a maintained current index.

Update the GraphQL schema by adding a category enum to the question model and push the changes to the Amplify API, regenerating code and queries.

Learn how to store images and videos in S3 with metadata in DynamoDB, enabling lookup and retrieval via Amplify, and implement a user profile with image upload.

Set up a user profile by creating a storyboard, adding a table view and navigation controller, and linking a bar button item with an icon to the user profile screen.

Connects a profile image view to storyboard controls, enables users to pick an image from the photo album, and prepares to save the selected image to S3 for the profile.

Learn to upload images to an S3 bucket from a Swift app, track upload progress, handle errors, and configure an auth role with Amplify for authenticated users.

Learn to integrate an existing DynamoDB table into your iOS app using AWS Amplify and AppSync by linking data sources, configuring permissions, and querying the table.

Expose all http methods through a single lambda using API Gateway proxy integration, enabling one lambda function to handle get, post, and other methods, with deployment via Amplify.

Test and verify a lambda behind api gateway using proxy integration, sending get and post requests with parameters, and monitor logs in cloud watch after amplify push.

Invoke a lambda from your iOS app by wiring API gateway, bridging header setup, and a Swift client to call a proxy endpoint with json body and query parameters.

Upgrade the amplify cli to the latest version and migrate your project. Resolve permission and ownership issues to ensure a safe upgrade that updates CloudFormation API calls without data loss.
