Comments
  • Please double check your UITableView outlet is connected properly
  • @Kuldeep yes outlet is connected properly
  • @SanjayMishra Please check your Outlet of UITableView not connected with multiple ViewControllers.
  • tblProjectList is the only thing that can be unwrapped on that line, so it is nil. Put a breakpoint on that line to prove it. Then, it's either connected wrongly or not at all. Remove the connection and reapply it.
  • check every variable you force to unwrap. Check your connections, do not forget to delegates. It's so fundamental mistake, for first 3-4 times follow to tutorials will be helpful
  • Then place a breakpoint just before the crash and try po(tblProjectList) in debugger console. If it doesn't print the table information then you are doing something wrong. Try to add the tableview again and create its outlet and then try.
  • I have already added it class ProjectsListViewController: UIViewController, UITableViewDataSource, UITableViewDelegate
