Get a LinkedIn post or article details using Swift. This comprehensive guide will walk you through the entire process, from setup to implementation.

Overview

What You'll Learn

  • Setting up your Swift environment
  • Installing the required HTTP client
  • Authenticating with SociaVault API
  • Making requests to LinkedIn
  • Handling responses and errors

What You'll Get

  • Access to post data
  • JSON formatted responses
  • Real-time data access
  • Scalable solution
  • Error handling patterns

Prerequisites

1. API Key

First, you'll need a SociaVault API key to authenticate your requests.

2. Development Environment

Make sure you have the following installed:

  • Swift installed
  • A code editor (VS Code, Sublime, etc.)
  • Command line interface access

Implementation

Step 1: Install HTTP Client

We'll use URLSession to make HTTP requests.

bash
// Standard library

Step 2: API Implementation

Now let's make a request to the LinkedIn API using Swift. Replace YOUR_API_KEY with your actual API key.

swift
import Foundation

let url = URL(string: "https://api.sociavault.com/linkedin/post?url=https%3A%2F%2Fwww.linkedin.com%2Fposts%2F...")!
var request = URLRequest(url: url)
request.httpMethod = "GET"
request.addValue("YOUR_API_KEY", forHTTPHeaderField: "x-api-key")
request.addValue("application/json", forHTTPHeaderField: "Content-Type")

let task = URLSession.shared.dataTask(with: request) { data, response, error in
    if let data = data {
        if let json = try? JSONSerialization.jsonObject(with: data, options: []) {
            print(json)
        }
    }
}

task.resume()

Best Practices

Error Handling

Implement comprehensive error handling and retry logic for failed requests. Log errors properly for debugging.

Caching

Cache responses when possible to reduce API calls and improve performance. Consider data freshness requirements.

Security

Never expose your API key in client-side code. Use environment variables and secure key management practices.

Troubleshooting

401

Unauthorized

Check your API key is correct and properly formatted in the x-api-key header.

402

Payment Required

You ran out of credits and need to buy more.

404

Not Found

The resource (user, video, etc.) might not exist or be private.

429

Too Many Requests

You have exceeded your rate limit. Slow down your requests.
