I guess in your case I would bind directly the response from your API to the model, so u can react to it.
In your API you could send the publisher directly, and drive it across the view model to the actual view.
import Combine
class APIClient: NSObject {
var cancellable: AnyCancellable?
let sharedSession = URLSession.shared
func fetchData(urlStr: String) -> AnyPublisher<[MyModel], Error> {
guard let url = URL(string: urlStr) else {
return
}
let publisher = sharedSession.dataTaskPublisher(for: url)
cancellable = publisher
.tryMap { [unowned self] result in
let decoder = JSONDecoder()
return try decoder.decode([MyModel].self, from: result.data)
}
.eraseToAnyPublisher()
}
}
import Foundation
class ViewModel: NSObject {
@IBOutlet var apiClient: APIClient!
func getGitData() -> AnyPublisher<[MyModel], Error> {
let urlStr = "https://api.github.com/repos/ReactiveX/RxSwift/events"
return apiClient.fetchData(urlStr: urlStr)
}
}
import UIKit
import Combine
class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
// MARK: - Variables
var cancellables: [AnyCancellable]
var viewModel: ViewModel!
@Published var models = [MyModel]()
// MARK: - IBOutlet
@IBOutlet weak var tableView: UITableView!
// MARK: - Life cycle
override func viewDidLoad() {
super.viewDidLoad()
viewModel.getGitData()
.sink { completion in
guard case .failure(let error) = completion else { return }
print(error)
} receiveValue: { (result) in
DispatchQueue.main.async { [weak self] models in
guard let strongSelf = self else { return }
strongSelf.models = models
}
}
.store(on: $cancellables)
$models()
.sink { _ in
self.tableView.reloadData()
}
.store(on: $cancellables)
}
// MARK: - TableView
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return models.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell")
let dataModel = models[indexPath.row]
cell?.textLabel?.text = dataModel.id
cell?.detailTextLabel?.text = dataModel.type
return cell!
}
}

One of the problems that I have is that I don't have insights on what the error on the thread means. Do you still have a definition of what could be happening?
I opened a bug report with the id FB15776080
Thanks!
