Hallo,
<div class=""><br class=""></div>
<div class="">I have a very simple suggestion. And I’m not very
sure then it haven’t been discussed already, so I’m sorry if that
is the case.</div>
<div class="">I would like to see the ability to just add code to
base methods instead of overriding it and calling supers method. So
basically an extension for methods.</div>
<div class=""><br class=""></div>
<div class="">Example:</div>
<div class=""><br class=""></div>
<div class="">Now:</div>
<div class="">override func viewDidLoad() {</div>
<div class="">super.viewDidLoad()</div>
<div class=""><i class="">// Your code</i></div>
<div class="">}</div>
<div class=""><br class=""></div>
<div class="">Suggestion:</div>
<div class="">addinto func viewDidLoad() {</div>
<div class=""><i class="">// Your code</i></div>
<div class="">}</div>
<div class=""><br class=""></div>
<div class="">My reasons:</div>
<div class="">1. Its very verbose about your intentions, which fits
into Swift style. The thing you actually want is not overriding but
appending. </div>
<div class="">2. You cannot make the mistake of forgetting to call
the supers method.</div>
<div class="">3. It open ways to introducing ‘semi-final’ methods,
which cannot be override but you still can append to
it. </div>
<div class=""> This to make sure your API
implementation will always be executed . I’m thinking about a
keyword like extendable to specify that you can only add to
it.</div>
<div class="">4. Less code.</div>
<div class=""><br class=""></div>
<div class="">I can’t think of any cons... Thought I can imagine
that the benefits are quite small and maybe not worth the
effort.</div>
<div class="">I would like to read some thoughts about this. Thank
you!</div>
<div class=""><br class=""></div>
<div class="">Kind regards,</div>
<div class="">Mustafa Sabur</div>
