Initialising model object without optionals
The model object is populated using JSONDecoder method. Since it is needed to pass it on tableview i need to initialise a local variable of type KBArticle on UI side. Is there any possible method of initialising an object of the KBArticle without optionals or accessing the inner array directly ?
var kbArticle = KBArticle()
Missing argument for parameter 'from' in call. Insert 'from: <#Decoder#>'
/// UI Side
var kbArticle = KBArticle()
override func viewDidLoad() {
super.viewDidLoad()
/// Web services call method
SDKCore.getInstance.getKbService().fetchKbArticles(with: topicID) { (result) in
switch result {
case .success(let kbArticle):
self.kbArticle = kbArticle
DispatchQueue.main.async {
self.tableView.reloadData()
}
case .failed(let e):
print("Error=(e)")
}
}
}
// Model Class in SDK
public struct KBArticle: Codable {
public let id: Int
public let topic: String
public let articleCount: Int
public let articles: [Article]
}
public struct Article: Codable {
public let id: Int
public let subject: String
}
/// Method in SDK
public func fetchKbArticles(with topicId: Int, completionHandler: @escaping (ResultModel<KBArticle, Error>) -> Void) {
let request = GetKBArticles(topicId: topicId)
Networking.shared.performRequest(request) { (response) in
switch response {
case .success(let response):
do {
let decoder = JSONDecoder()
let result = try decoder.decode(KBArticle.self, from: response.data!)
completionHandler(.success(result))
} catch let error {
completionHandler(.failed(error))
}
case .failed(let error):
completionHandler(.failed(error))
}
}
}
I have to use this articles inside kbArticle struct to provide my tableview datasource. Is is possible to initialise kbArticle object without a primary initialisation using nil values???

If you need new object without optional , you can set a default value for all params
ex :
public struct KBArticle: Codable {
public var id: Int = 0
public var topic: String = ""
public var articleCount: Int = 0
public var articles: [Article]?
}
public struct Article: Codable {
public var id: Int = 0
public var subject: String = ""
}
Use: let myObj = KBArticle()
