This tutorial teaches you how to build a GPT client for iOS using SwiftUI. The tutorial covers how to send a request to the OpenAI GPT API and decode the JSON response to display the generated text.

Note that this tutorial will focus on the logic for sending and receiving requests to and from the OpenAI GPT API, and will not cover all the UI details involved in building the app.

For the full code, including the UI implementation, you can visit my Github repo containing working code samples for creating iOS and Android apps

What is GPT?

GPT, or Generative Pre-trained Transformer, is a type of machine learning model that is capable of generating natural language text. It is a type of language model that has been pre-trained on large amounts of text data, and can be fine-tuned for specific tasks, such as generating text in response to a prompt.

What will we build?

We will build an app that takes a user input from a TextField, sends it to the GPT API, receives the response, and decodes the JSON in order to display the answer as animated Text. The sendRequest function is responsible for communicating…
