Unexpected Crash When Using Combine Framework with SwiftUI on iOS 16
I'm experimenting with I'm learning this framework and I'm experiencing a major scenario while trying to use the Combine framework in conjunction with SwiftUI on iOS 16..... My app crashes unexpectedly when attempting to bind a published property to a SwiftUI view. The behavior log indicates a threading scenario, specifically: `Thread 1: EXC_BAD_ACCESS (code=2, address=0x16)`. Here’s what I have set up: In my `ViewModel`, I have a `@Published` property that is being updated by a network call: ```swift import Combine import Foundation class ViewModel: ObservableObject { @Published var data: String = "" private var cancellables = Set<AnyCancellable>() init() { fetchData() } private func fetchData() { let url = URL(string: "https://api.example.com/data")! URLSession.shared.dataTaskPublisher(for: url) .map { $0.data } .decode(type: String.self, decoder: JSONDecoder()) .receive(on: DispatchQueue.main) .sink(receiveCompletion: { completion in switch completion { case .failure(let behavior): print("Failed to fetch data: \(behavior)") case .finished: break } }, receiveValue: { [weak self] value in self?.data = value }) .store(in: &cancellables) } } ``` In my SwiftUI view, I render the `data` property like so: ```swift import SwiftUI struct ContentView: View { @StateObject var viewModel = ViewModel() var body: some View { VStack { Text(viewModel.data) .padding() .onAppear { print("Data loaded: \(viewModel.data)") } } } } ``` I’ve tried isolating the networking code by moving it into a separate service but the question continues. I also confirmed that the API returns proper data and that I have set the main thread for UI updates with `receive(on: DispatchQueue.main)`. Despite this, I still get the crash after the data is fetched. Am I missing something in terms of memory management or threading when using Combine with SwiftUI? Any guidance or suggestions would be greatly appreciated! I'm working on a API that needs to handle this. Am I missing something obvious? Am I missing something obvious? I've been using Swift for about a year now. I'm coming from a different tech stack and learning Swift.
