Answer 1

You stated that progressHUD is retained by the owning view controller (self) and you reference it in your closure...so add it to the capture list and then use the captured variable in the closure as follows:

object.setCompletionHandler { [weak self] (error) -> Void in
    if(!error){
        self?.tableView.reloadData()
    }
    self?.progressHUD.hide(false)
}
