ios - Adding Swift Closures as values to Swift dictionary -


I would like to make a swift dictionary that has string type keys and its values ​​in the form of closures. The following is the code I have, but it gives me an error:

'@lawlue' is not the same (string, () -> zero) '

  class commander {Private var command dict: [string: () - & gt; Zero]! Init () {self.setUpCommandDict (); } Func setUpCommandDict () {self.commandDict ["OpenAssessment_1"] = {println ("I'm locked inside"); }}}

I have tried to see other questions on stack overflow, but it does not give me any satisfactory answer. So I would appreciate some help here.

If you call your init before your setup function, Should work: 

  class CommandResolver {private var commandDict: [string: () - & gt; Zero] init () {commandDict = [:] setUpCommandDict ()} func setUpCommandDict () {commandDict ["OpenAssessment_1"] = {println ("I'm locked inside")}}}

Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ...
