I have a table to which I've added a refreshControl and when I pull down the table to refresh the data, I reset the array that feeds the table with data and then immediately request new data through an API call. Until now, I have used completion handlers and protocols to get the data into the table view but I want to move the logic to async/await because of the complexity needed by the network calls and the pyramid of nested closures. Populating the view in viewDidLoad works fine but with pullToRefresh selector I get an error: Thread 1: EXC_BAD_ACCESS (code=1, address=0xbcf917df8160) override func viewDidLoad() {     super.viewDidLoad()     setupView()     setupTableView()     setupTableRefreshControl()     Task {       await getBalances() //async network call       myTable.reloadData()     }   }    func setupTableRefreshControl() {     myTable.refreshControl = UIRefreshControl()     myTable.refreshControl?.addTarget(self, action: #selector(didPullToRefresh), for: .valueChanged)   } Code that crashes app:    @objc func didPullToRefresh() async {     balance.reset() // reset array to []     Task {       await getBalances() //async network call       myTable.reloadData()     }   }
