Hey Juhi, let's work through why you're not getting the job poster's profile avatar and fix this step by step!

The Core Issue #

Looking at your code and Postman screenshots, I notice you're currently passing company_logo to the detail view controller—but your goal is to display the job poster's personal registration avatar, not the company's logo.

From the Job Response screenshot, each job entry includes a user_id field. This is the key: you need to use this user_id to fetch the corresponding user's data (including their avatar) from your user API, not pull from the company array.

Step 1: Define a User Data Model #

First, create a Codable struct to parse the user API response (adjust field names to match your actual user endpoint):

struct UserData: Codable {
    let user_id: String
    let user_avatar: String // Replace with your actual avatar field name from the user API
    // Add any other user fields you might need
}

Make sure your JobData struct also includes the user_id field (since it's returned by the job API) so you can access it later.

Step 2: Fetch User Data & Pass Avatar to Detail View #

Update your didSelectRowAt method to fetch the user's avatar using the job's user_id, then pass it to the detail view:

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath){
    let selectedCell = tableView.cellForRow(at: indexPath)!
    selectedCell.contentView.backgroundColor = .white
    let jdata = jobFilteredArray[indexPath.row]
    
    // Grab the user_id from the selected job
    guard let userId = jdata.user_id else {
        print("No user ID found for this job")
        return
    }
    
    // Request user data from your user API
    guard let userApiUrl = URL(string: "http://172.16.1.22/Get-User-API/get-user/?user_id=\(userId)") else {
        print("Invalid user API URL")
        return
    }
    
    URLSession.shared.dataTask(with: userApiUrl) { [weak self] data, response, error in
        guard let self = self, error == nil, let data = data else {
            print("Failed to fetch user data: \(error?.localizedDescription ?? "Unknown error")")
            return
        }
        
        do {
            let userData = try JSONDecoder().decode(UserData.self, from: data)
            
            // Jump to detail view on main thread
            DispatchQueue.main.async {
                let jobDetail = WorkerJobDetailsViewController(nibName: "WorkerJobDetailsViewController", bundle: nil)
                
                // Populate all existing fields
                jobDetail.gender = self.jobArray[indexPath.row].job_emp_gender
                jobDetail.location = self.jobArray[indexPath.row].job_location
                jobDetail.companyName = (self.companyArray.first { $0.company_id == jdata.company_id }?.company_name)!
                jobDetail.skills = self.jobArray[indexPath.row].job_skills
                jobDetail.descriptionValue = self.jobArray[indexPath.row].job_desc
                jobDetail.jobDesignation = self.jobArray[indexPath.row].job_desig
                
                // Pass the user's avatar instead of company logo
                jobDetail.profile = userData.user_avatar
                
                self.present(jobDetail, animated: true, completion: nil)
            }
        } catch {
            print("Failed to decode user data: \(error)")
        }
    }.resume()
}

Step 3: Load the Avatar in the Detail View #

In WorkerJobDetailsViewController, add code to load the avatar image into your UIImageView. You can use basic URLSession or a library like Kingfisher for better caching/error handling:

Basic URLSession Approach:

override func viewDidLoad() {
    super.viewDidLoad()
    
    // Load avatar if profile path exists
    guard let avatarPath = profile, 
          let fullAvatarUrl = URL(string: "http://172.16.1.22/\(avatarPath)") else {
        // Set a default avatar if path is invalid
        avatarImageView.image = UIImage(named: "default-avatar")
        return
    }
    
    URLSession.shared.dataTask(with: fullAvatarUrl) { [weak self] data, response, error in
        guard let self = self, let imageData = data, error == nil else {
            self?.avatarImageView.image = UIImage(named: "default-avatar")
            return
        }
        DispatchQueue.main.async {
            self.avatarImageView.image = UIImage(data: imageData)
        }
    }.resume()
}

Kingfisher Approach (simpler, recommended):

If you use Kingfisher, just add this line to viewDidLoad:

avatarImageView.kf.setImage(with: URL(string: "http://172.16.1.22/\(profile ?? "")"), placeholder: UIImage(named: "default-avatar"))

Bonus Optimization #

To avoid making a new API call every time a cell is tapped, you can pre-fetch and cache all user data when you load the job list:

1. Collect all unique user_ids from jobArray
2. Make a bulk request to your user API (or individual requests)
3. Store user data in a dictionary like var userCache: [String: UserData] = [:]
4. Then in didSelectRowAt, just pull the avatar from the cache instead of making a new request
