Protocol-Oriented Programming in Objective-C

Posted on 2015-06-23 by Crusty Crustofferson

Hi, this is a guest post from Crusty. I’ve been doing a tour of the blogosphere, discussing Protocol-Oriented Programming. This time, Graham was kind enough to hand over the keyboard for SICPers and let me write a post here. Back … Continue reading →

Functional Programming in Object-Oriented Programming in Functional Programming in Swift

Posted on 2015-06-14 by Graham

The objects that I’ve been building up over the last few posts have arbitrarily broad behaviours. They can respond to any selector drawn from the set of all possible strings. As with all art, beauty is produced by imposing constraints. … Continue reading →

Classes in objects in object-oriented programming in functional programming in Swift

Posted on 2015-06-14 by Graham

So far, Objective-Swift objects have used prototypical inheritance, in which they supply some methods but also know about another object to which they can forward messages they don’t understand themselves. This pattern is used in languages like Self, JavaScript and … Continue reading →

Mutable objects in immutable objects in object-oriented programming in functional programming in Swift

Posted on 2015-06-12 by Graham

I didn’t realise this at the time, the previous entry wasn’t the last Objective-Swift post. The inheritance mechanism in ObjS is prototypical, meaning that an object inherits from a single other object rather than getting its behaviour from a class. … Continue reading →

This gist shows the result of doing the self-threading talked about at the end of the last post. Each method implementation takes an object pointer and a selector name, just like in the real world. That’s enough Objective-Swift for me. … Continue reading →

Further Advances in Objective-Swift

Posted on 2015-06-06 by Graham

Previously on SICPers, I defined objects as functions that return methods and built dynamic method dispatch in this object system. It’s time to tie up some loose ends. Proper selectors In languages like Smalltalk and Objective-C, an object’s range isn’t … Continue reading →
