Should we use observer methods to modify IBOutlet properties

Question

I have seen code where IBOutlets modify their properties using a didSet like so..

@IBOutlet private weak var tableView: UITableView! {
    didSet {
        tableView.dataSource = self
        tableView.delegate = self
    }
 }

Is this considered good practice, or should we create a configure method in viewDidLoad?

Answer 1

Actually didSet here

outer part 
   didSet { 
     // refresh
  }

makes more sense if the outer var you observe is rapidly changing / real time so you need to react to this change , but for the current case which is the table is set only once from IB inner init using didSet has no bounce over putting the code inside viewDidLoad
