swift error: Value of type _ has no member _


how do I fix this error? xcodes-13

This Is my code for working with api:

struct everything: Codable{
        let topic: String
        let content: String
        let category: String
        let time: String
        let price: String
        let prize: String
    }    
    struct parsingss : Codable {
        let scrims: [everything]
    }
    
    @IBOutlet weak var prizeLabel: UILabel!
    @IBOutlet weak var priceLabel: UILabel!
    @IBOutlet weak var timeLabel: UILabel!
    @IBOutlet weak var categoryLabel: UILabel!
    @IBOutlet weak var ContentLabel: UILabel!
    @IBOutlet weak var TopicLabel: UILabel!
    

    override func viewDidLoad() {
        super.viewDidLoad()
        
        if let url = URL(string: "http://{Local-Host}/post") {
           URLSession.shared.dataTask(with: url) { data, response, error in
        if let data = data {
            let jsonDecoder = JSONDecoder()
            do {
            let parsedJSON = try jsonDecoder.decode(parsingss.self, from: data)
                
                print(parsedJSON)
                
                DispatchQueue.main.async {

                    self.TopicLabel.text = parsedJSON.topic
                    self.ContentLabel.text = parsedJSON.content
                    self.categoryLabel.text = parsedJSON.category
                    self.timeLabel.text = parsedJSON.time
                    self.priceLabel.text = parsedJSON.price
                    self.prizeLabel.text = parsedJSON.prize
                    
                   }
                    }
            catch {
            print(error)
                        
                    }
                   }
               }.resume()
            }
    }
}

"error : Value of type 'testViewController.parsingss' has no member 'topic'"

Reply with some codes would be better either ways. Thanks developers.

Without "trying to print in label", the result does come to the output. it is in an array:

[ scrims: {
        "topic": "tv",
        "content": "done",
        "category": "gg",
        "time": "10pm",
        "price": "Rs.100",
        "prize": "Rs.1000",
        "id": 1
    },
    {
        "topic": "1",
        "content": "d1",
        "category": "g1",
        "time": "10pm",
        "price": "Rs.11",
        "prize": "R1",
        "id": 2
    } ]

Thanks!


Solution

  • You are trying to assign the subscript values from an array object without specifying the index.

    Try this:

    class ViewController: UIViewController {
    @IBOutlet weak var prizeLabel: UILabel!
    @IBOutlet weak var priceLabel: UILabel!
    @IBOutlet weak var timeLabel: UILabel!
    @IBOutlet weak var categoryLabel: UILabel!
    @IBOutlet weak var ContentLabel: UILabel!
    @IBOutlet weak var TopicLabel: UILabel!
    
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        if let url = URL(string: "http://{Local-Host}/post") {
            URLSession.shared.dataTask(with: url) { data, response, error in
                if let data = data {
                    do {
                        let parsedJSON = try JSONDecoder().decode(parsingss.self, from: data)
                        
                        print(parsedJSON)
                        
                        DispatchQueue.main.async {
                            self.TopicLabel.text = parsedJSON.scrims[0].topic
                            self.ContentLabel.text = parsedJSON.scrims[0].content
                            self.categoryLabel.text = parsedJSON.scrims[0].category
                            self.timeLabel.text = parsedJSON.scrims[0].time
                            self.priceLabel.text = parsedJSON.scrims[0].price
                            self.prizeLabel.text = parsedJSON.scrims[0].prize
                        }
                    }
                    catch {
                        print(error)
                        
                    }
                }
            }.resume()
        }
    }
    

    }
