What is the purpose of having 'launch' menuitem in dropdown when viewing controller code because if I write there code it is not executed and I should add Basic Function with the name 'onLaunch' to run my code.
Also when I add 'onLaunch' function to controller I get red exclamation mark to the right of the function in project inspector saying: 'This function is overriding a member', but here is it said that 'Feel free to override it in child classes'.
