Build ChatGPT App for iOS/macOS with SwiftUI in 1 Hour

Set up a single empty project with iOS and macOS targets, add a shared group, integrate the OpenAI swift package for both targets, and register an OpenAI key.

Register on the OpenAI platform to obtain API keys, sign up with Google, view or create a new secret key, and securely save it since it can’t be viewed again.

Design a simple SwiftUI chat interface for iOS and macOS that sends user input to ChatGPT using the OpenAI Swift package, then displays answers and validates input.

Set up a core data stack with a singleton core data manager to store questions and answers offline using a history item entity, and inject the view context into SwiftUI.

Model a query with a question and answer, and save it to SQLite via Core Data in a SwiftUI app. Persist queries with a history item and data manager.

Display the history of questions by adding a history view that fetches and lists questions from Core Data, sorted by date created, in a shared SwiftUI iOS/macOS app.

Select a history item to display its question and answer in the main view, updating the shared model via an environment object and dismissing the history view.

Enable automatic scrolling in a SwiftUI chat interface by wrapping content in a scroll view and using ScrollViewReader with a proxy to scroll to the last query ID.

Run and debug a SwiftUI macOS app, using a navigation split view with history and detail, and enable the Mac app to make outbound connections.

Convert a macOS app into a toolbar app by adding an app delegate, a status item, and a popover that hosts the content view.

Add a centered overlay progress view controlled by an isSearching state to indicate ongoing ChatGPT queries in a shared iOS/macOS SwiftUI view, using an OpenAI Swift library integration.

Create iOS and macOS apps using OpenAI Swift to integrate ChatGPT, including FAQ-style interactions. Extend to the web with libraries for React, Angular, Vue, and Next.js.
