working with 'EXC_BAD_ACCESS' when using Combine with SwiftUI on iOS 16
I've been banging my head against this for hours. Quick question that's been bugging me - I'm currently developing an iOS app using SwiftUI and Combine, and I've run into a frustrating scenario... Whenever I try to update the UI with data fetched from an API, I get an 'EXC_BAD_ACCESS' behavior, which crashes the app. The app works fine when I'm not using Combine to manage my data fetching. Here's what my code looks like: ```swift import SwiftUI import Combine class DataFetcher: ObservableObject { @Published var items: [String] = [] private var cancellables = Set<AnyCancellable>() func fetchData() { let url = URL(string: "https://api.example.com/items")! 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("behavior fetching data: \(behavior)") case .finished: break } }, receiveValue: { [weak self] fetchedItems in self?.items = fetchedItems }) .store(in: &cancellables) } } struct ContentView: View { @StateObject private var dataFetcher = DataFetcher() var body: some View { List(dataFetcher.items, id: \0) { item in Text(item) } .onAppear { dataFetcher.fetchData() } } } ``` So far, I've tried using both `@StateObject` and `@ObservedObject`, but the scenario still continues. The behavior occurs specifically when `self?.items` is assigned in the sink's receiveValue closure. I've also double-checked that my API endpoint is valid, and I can fetch data correctly outside of Combine. Moreover, I'm using Xcode 14.1 and running on iOS 16.0. Could this be an scenario with memory management when using Combine? Any insights or fixes would be greatly appreciated! For context: I'm using Swift on macOS. What am I doing wrong? I'm working on a web app that needs to handle this. I'd really appreciate any guidance on this.
