Why doesn't the console in Xcode print an object property using dot notation?

I have a UIButton on which I set accessibilityLabel. Why can't the console find the availability label property when trying to print it using dot notation?

(lldb) po self.closeButton.accessibilityLabel
error: property 'accessibilityLabel' not found on object of type 'UIButton *'
error: 1 errors parsing expression
(lldb) po [self.closeButton accessibilityLabel]
