Is there such thing as 'didGet' in Swift? A method that is run whenever a variable is accessed? -

basically, want this:

var counter : int = 0; private var _data : string; var data : string {     { counter += 1; return _data; }     set { _data = newvalue; } } 

then want reduce this:

var counter : int = 0; var data : string {     { counter += 1; return data; }     set { data = newvalue; } } 

but noticed can't done. (error: variable used within initial value). want simplify this:

var counter : int = 0; var data : string {     didget { counter += 1; } } 

but there's no such thing didget. there way without adding new other variable? need run counter += 1 every time data accessed, without adding new variable storage. thanks.

no, there no way without adding new variable.

if return in get method of variable same variable, create infinite loop.
