task?.cancel()
task = session.dataTask(with: QuoteService.pictureUrl) { (data, response, error) in
DispatchQueue.main.async {
guard let data = data, error == nil else {
callback(false, nil)
return
}
guard let response = response as? HTTPURLResponse, response.statusCode == 200 else {

First, please don't use screenshots do show your code. If you want help, others typically copy/paste your code to check whats wrong with it.
There are some minor issues with your code. Some hints from me:
Start your types with a big letter, like ImageLogo not imageLogo:
Avoid statics
Avoid singletons (they are almost statics)
Hand in the pictureUrl into getQuote
struct ImageLogo {
var image:Data
}
class QuoteService {
private var task: URLSessionDataTask?
func getQuote(from pictureUrl:URL, callback: #escaping (Bool, ImageLogo?) -> Void) {
let session = URLSession(configuration: .default)
task?.cancel()
task = session.dataTask(with: pictureUrl) {
(data, response, error) in
DispatchQueue.main.async {
guard let data = data, error == nil else {
callback(false, nil)
return
}
guard let response = response as? HTTPURLResponse, response.statusCode == 200 else {
callback(false, nil)
return
}
let quote = ImageLogo(image: data)
callback(true, quote)
print(data)
}
}
task?.resume()
}
}
Store an instance of QuoteService in your view controller
Call getQuote on that instance, handing in the pictureUrl
class ViewController : UIViewController {
var quoteService:QuoteService!
override func viewDidLoad() {
self.quoteService = QuoteService()
}
func toggleActivityIndicator(shown:Bool) { /* ... */ }
func update(quote:ImageLogo) { /* ... */ }
func presentAlert() { /* ... */ }
func updateconcept() {
guard let url = URL(string:textField.text!) else {
print ("invalid url")
return
}
toggleActivityIndicator(shown:true)
quoteService.getQuote(from:url) {
(success, quote) in
self.toggleActivityIndicator(shown:false)
if success, let quote = quote {
self.update(quote:quote)
} else {
self.presentAlert()
}
}
}
/* ... */
}
Hope it helps.

I think you want to pass textfield Text(URL Enter By user) in Web Services
Add a parameter url_str in getQuote function definition first and pass textfield value on that parameters
fun getQuote(url_str : String, callback : #escaping(Bool, ImgaeLogo/)->void){
}
