Issue with UIButton State Not Updating After Asynchronous Network Call in iOS 17
I'm wondering if anyone has experience with I'm working on a personal project and I tried several approaches but none seem to work..... I'm facing an issue where the state of a UIButton does not update correctly after making an asynchronous network call in my iOS 17 app. I have a button that is supposed to show a loading state while fetching data from an API. After the network request completes, I want to update the button's title and enable/disable it based on the success of the fetch. Here’s a simplified version of my code: ```swift @IBOutlet weak var fetchButton: UIButton! @IBAction func fetchData(_ sender: UIButton) { fetchButton.setTitle("Loading...", for: .normal) fetchButton.isEnabled = false fetchDataFromAPI { success in DispatchQueue.main.async { if success { self.fetchButton.setTitle("Fetched Successfully", for: .normal) self.fetchButton.isEnabled = true } else { self.fetchButton.setTitle("Retry", for: .normal) self.fetchButton.isEnabled = true } } } } func fetchDataFromAPI(completion: @escaping (Bool) -> Void) { let url = URL(string: "https://api.example.com/data")! let task = URLSession.shared.dataTask(with: url) { data, response, error in if let error = error { print("Error: \(error)") completion(false) return } // Handle data... completion(true) } task.resume() } ``` The issue is that when I tap the button, it immediately shows the loading state, but sometimes it stays in that state even after the network call completes and I try to update the title and enable it again. I’ve checked for any main thread issues and ensured the UI updates are on the main thread, but I still see inconsistent behavior. Occasionally, I see the title not updating at all, and I get no error messages logged. I’ve also tried wrapping the `fetchDataFromAPI` call within a `DispatchQueue.main.async` block, but it didn’t make a difference. Has anyone experienced something similar or have any suggestions on what to look for? I'm working on a web app that needs to handle this. Am I missing something obvious? Any help would be greatly appreciated! Any help would be greatly appreciated! I'm working with Swift in a Docker container on Linux. Could this be a known issue? I'm developing on Ubuntu 20.04 with Swift. I'd really appreciate any guidance on this.
