I'm trying to get channel's icons from YouTube API in my Swift test app, but I don't know how to properly display such images (they have no extensions to them), and how to convert them. My search in the internet gave no results.
Here you can check it out
The result YouTube api gives is not .png .jpg file, please check "thumbnails" "url" has no extension to it

However Postman (https://www.postman.com/) is able to display image somehow. But if I copy and paste "image url"
https://yt3.ggpht.com/ytc/AMLnZu-oDvWEJ-WfN9bgxQB2YAlnjC2uqN_c7JQZvX9Ikfg=s800-c-k-c0x00ffffff-no-rj
into my browser, nothing happends -> page not loads, and the same happens in my swift app.
If anybody knows solution, your help is eally appreciated!
UPDATE to Ameermuhammed:
Adding logs. Something is wrong. I want to note that I'm not using Auth 2.0 with api, but requesting data only with dedicated API key YouTube provided me with. However this shouldn't be the case since Postman is still able to load image. For now I'm trying to figure it out

UPDATE 2: The problem is probably with encryption and secure connection, but so far i couldn't find a solution to fix it It should be probably something with info.plist

Use this extension on UIImageView:
File - UIImageView Extension.swift
extension UIImageView {
func download(from url: URL, contentMode mode: ContentMode = .scaleAspectFit) {
contentMode = mode
URLSession.shared.dataTask(with: url) { data, response, error in
guard
let httpURLResponse = response as? HTTPURLResponse, httpURLResponse.statusCode == 200,
let mimeType = response?.mimeType, mimeType.hasPrefix("image"),
let data = data, error == nil,
let image = UIImage(data: data)
else { return }
DispatchQueue.main.async() { [weak self] in
self?.image = image
}
}.resume()
}
func downloadFromUrlString(from link: String, contentMode mode: ContentMode = .scaleAspectFit) {
guard let url = URL(string: link) else { return }
download(from: url, contentMode: mode)
}
}
Now in view controller pass image url:
File - ViewController.swift
@IBOutlet weak var imageView: UIImageView!
override func viewDidLayoutSubviews() {
super.viewDidLayoutSubviews()
imageView.downloadFromUrlString(from: "https://yt3.ggpht.com/ytc/AMLnZu-oDvWEJ-WfN9bgxQB2YAlnjC2uqN_c7JQZvX9Ikfg=s800-c-k-c0x00ffffff-no-rj", contentMode: .scaleToFill)
}

Finally got it working
- Added this to my info.plist
<key>NSAppTransportSecurity</key> <dict> <key>NSExceptionDomains</key> <dict> <key>yt3.ggpht.com</key> <dict> <key>NSExceptionRequiresForwardSecrecy</key> <false/> <key>NSIncludesSubdomains</key> <true/> <key>NSTemporaryExceptionAllowsInsecureHTTPLoads</key> <true/> <key>NSTemporaryExceptionMinimumTLSVersion</key> <string>TLSv1.1</string> </dict> </dict> </dict>
replaced https to http
let channelImageUrl = pair.channelInfo.snippet.thumbnails.medium.url.replacingOccurrences(of: "https", with: "http")
Combined it with answer of ameermuhammed
Result: Images are loading
