While I believe abstract methods can be a great addition for dealing with contract-like constructs in object-oriented languages, they seem out-of-place in Swift, which is a protocol-oriented language. Adding abstract methods to Swift would encourage lazy developers to use them instead of protocols and value types. <div class=""><br class=""></div><div class=""><blockquote type="cite" class="">Is the problem being addressed significant enough to warrant a change to Swift?</blockquote><div class=""><br class=""></div>Yes.</div><div class=""><br class=""></div><div class=""><blockquote type="cite" class=""><div class="" style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space;"><div class="">Does this proposal fit well with the feel and direction of Swift?</div></div></blockquote><div class=""><br class=""></div>No. I believe it doesn't fit well in the direction Swift is taking.<br class=""><div class=""><br class=""></div><div class=""><blockquote type="cite" class="">If you have used other languages or libraries with a similar feature, how do you feel that this proposal compares to those?</blockquote><br class=""></div><div class="">Yes, PHP. While I must say that abstract classes and methods were a common and powerful tool in PHP, they do not fit well in Swift, which offers a much more powerful alternative – protocols.</div><div class=""><br class=""></div><div class=""><blockquote type="cite" class="">How much effort did you put into your review?
