2. Add the Key to Your Project: Open your Xcode project and navigate to where you manage configuration settings. You’ll need to securely store your API key. One common approach is to use a configuration file or environment variables.
3. Implement the Key in Your Code: When making API requests, include the API key in the header. Here’s a quick example in Swift using Alamofire:

import Alamofire

let headers: HTTPHeaders = [
    "Authorization": "Bearer YOUR_API_KEY"
]

AF.request("https://api.openai.com/v1/engines/davinci-codex/completions", headers: headers).responseJSON { response in
    // Handle response
}

Test Your Configuration: Ensure that your API key is correctly integrated by running a test request. Check for any errors and verify that you’re receiving the expected responses.

Similar to verifying the components of a recipe before diving into it make sure your API key is set up properly to prevent any glitches in how your application runs.

4. Implement Features: Add features that utilize the ChatGPT API. For instance, you can implement text fields for user input and display responses in a chat-like format. Here’s a simple example of sending user input to the API and displaying the response:

func sendRequest(userInput: String) {
    let parameters: [String: Any] = [
        "prompt": userInput,
        "max_tokens": 150
    ]
    
    AF.request("https://api.openai.com/v1/engines/davinci-codex/completions", method: .post, parameters: parameters, encoding: JSONEncoding.default, headers: headers).responseJSON { response in
        // Update UI with response
    }
}

Test Your App: Run your app on the simulator or a real device. Check all functionalities, from user input to API responses. Debug any issues that arise to ensure a smooth user experience.

Creating this application can be a fulfilling journey similar to creating a stunning artwork. Every line of code and every functionality contributes a sprinkle of your imagination to the end result.
