Text not displaying from JSON in Swift - json

Question

import UIKit
let cellid = "cell"
class Post {
var videoName: String?
var videoDescription: String?
}
class VideoFeedController: UICollectionViewController, UICollectionViewDelegateFlowLayout {
var posts = [Post]()
var json: [Any]?
var names: [String] = []
var contacts: [String] = []
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
let CatagoryMain = Post()
CatagoryMain.videoDescription = "example text"
CatagoryMain.videoName = "wewewewew"
posts.append(CatagoryMain)
collectionView?.backgroundColor = UIColor.white
navigationItem.title = "Main Video Feed"
collectionView?.alwaysBounceVertical = true
collectionView?.register(VideoFeedCell.self, forCellWithReuseIdentifier: cellid)
let urlString = "example url"
let url = URL(string: urlString)
URLSession.shared.dataTask(with:url!) { (data, response, error) in
if error != nil {
print("failed")
} else {
do {
let parsedData = try JSONSerialization.jsonObject(with: data!, options: []) as! [String:Any]
let currentVideo = parsedData["video"] as! [String:Any]
if let currentVideoTitle = currentVideo["title"] as? String {
print(currentVideoTitle)
// have text display instead of wewewew and example text
}
} catch let error as NSError {
print(error)
}
}
}.resume()
}
So for now it says example text for the video description and wewewewew for the video name and those display fine.I am trying to get the info from the json though so instead of example text it would have the description and instead of wewewewew it would have the video name I thought it would go like this
if let currentVideoTitle = currentVideo["title"] as? String {
print(currentVideoTitle)
CatagoryMain.videoDescription = "\(currentVideoTitle)"
CatagoryMain.videoName = "\(currentVideoTitle)"
posts.append(CatagoryMain)
}
however that was wrong and if I do that nothing shows on the screen besides the navigation bar and the title for the navigation bar. Thank you in advance if you can help! The actual title does show in the console by the way.

Like the comment I left above, we need more code to figure out the situation and help you out :) And your question is a little bit unclear.

besides the navigation bar and the title for the navigation bar.
You mean the UICollectionView is not loading the data? or the data are not loaded into posts array? is collectionView even init-ed?
Also, would like to have a look of the parsedData object. As you are using collectionView which means you want to display multiple cells. But your parsing codes do not look like you are parse an array of objects.(but only one object??)
Quick advice,
1. Print out the posts.counts to see if there are data?
2. If there is any data, add collectionView.reloadData() after you added data to posts.
