xcode - Arrays and Swift -


I am trying to deal with an app in Swift and I'm experiencing the following error using the array Fatal error: Out of range index range

it appears that when an app assigns a value to index 0:

Dracin: square: {init (CGSize size) {super.init (size: size)} var line = SKShapeNode () var path = CGPathCreateMutable () var touch: UITouch! Var pts = [CGPoint] () touches the override function (touch: nsset, event event: uievent) {/ * when touch starts / touch / touch.onebase ()) as UIT! Self.pts [0] = touch.locationInNode (self) & lt; - Error appears here DrawLine ()}

Some thoughts? (I'm using Xcode 6 Beta 4)

Your array is already empty. 

  if self.pts.isEmpty {self.pts.append (touch.locationInNode (self)}} other {self.pts [0] = touch.locationInNode (self)}

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. 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...
