Swift OpenAI API Integration: Setting Up Authorization with API Key

To provide an API key in Swift, you can use the Authorization header with Bearer authentication. Here's an example of how you can do it:

import Foundation

func makeRequest() {
    // API Key
    let apiKey = 'YOUR_API_KEY'
    
    // API Endpoint
    let url = URL(string: 'https://api.openai.com/v1/your-endpoint')!
    
    // Request
    var request = URLRequest(url: url)
    request.httpMethod = "GET"
    request.addValue("Bearer (apiKey)", forHTTPHeaderField: "Authorization")
    
    // Send Request
    let task = URLSession.shared.dataTask(with: request) { (data, response, error) in
        if let error = error {
            print("Error: (error)")
            return
        }
        
        // Handle Response
        if let data = data {
            let responseString = String(data: data, encoding: .utf8)
            print("Response: (responseString ?? "")")
        }
    }
    
    task.resume()
}

// Call the function
makeRequest()

Make sure to replace 'YOUR_API_KEY' with your actual API key obtained from https://platform.openai.com/account/api-keys. Additionally, replace 'https://api.openai.com/v1/your-endpoint' with the appropriate API endpoint you want to access.
