Произошла ошибка SSL, но данные получены

1 голос
/ 29 января 2020

Я перепробовал много опций, в том числе и те, которые представлены в stackoverflow, и ничего не помогло. Если я не вхожу в свое приложение в течение одного часа или более, я получаю сообщение об ошибке ssl, и мой метод не выполняется. 

        test.getModelFromQuarter { (result) in
        if result {
            print("*********SUCCESS********")

            DispatchQueue.main.async {
                self.setChart(dataPoints: self.test.getDataPoint(for: .week), values: self.test.getDefaultCCY(from: .week)!.values)

                self.activityIndicator.stopAnimating()

                self.currencyBanner.text = "НБУ - \(self.test.getDefaultCCY(from: .week)!.values.last!) \(self.test.getDefaultCCY(from: .week)!.ccy)"

                self.setComparingImage(firstValue: (self.test.getDefaultCCY(from: .week)?.values.last)!, secondValue: (self.test.getDefaultCCY(from: .week)?.values.dropLast().last)!)
            }
        }

Это метод с проблемой. 

    func load(url: String, handler: @escaping ([CCYModel]) -> Void) {
    var ccyModels: [CCYModel] = []

    Alamofire.request(url).responseJSON { (response) in
        if response.result.isSuccess {
            if let json = try? JSON(response.result.value!) {

                if let array = json.array {
                    for json in array {
                        let model = CCYModel(ccy: json["cc"].stringValue, rate: json["rate"].doubleValue)
                        ccyModels.append(model)
                    }
                }
            }
        } else {
            print("*************************")
            print("Fetching currencies error \(response.result.error)")
            print("*************************")
        }

        handler(ccyModels)
    }
}

Это можно исправить путем перезапуска приложения или «перезагрузки пользовательского интерфейса», что означает, что данные с сайта успешно загружены .

Это мой список, где я пытался решить проблему.

Возможно ли для xcode игнорировать эту ошибку? Поскольку мое приложение работает нормально, данные загружаются. Просто метод в viewDidLoad иногда не загружает пользовательский интерфейс.
