You'll only be able to effectively apply POP-principles if you understand how protocol extensions, protocol composition, and protocol inheritance works. In this short video, I talk about protocol inheritance. https://youtu.be/6LDvgJhK2oI Are you interested in Swift and Protocol-Oriented Programming?

Swift 4 Limited @objc Inference – A Monster Lurking in the Dark

By | 2017-09-21T08:51:41+00:00 September 21st, 2017|Swift 4, Swift Programming|0 Comments

So, you downloaded the shiny new Xcode 9 and migrated your project to Swift 4. As hinted, you disabled @objc inference right away: Then, subtle issues may have popped up. For example, this KVO-based code - which ran beautifully under Swift 3 - suddenly stopped working: for (key, value) in jsonDict { if self.value(forKey: key) != nil { self.setValue(value, forKey: key) } } According to my best knowledge, here are the options to fix the problem: Re-enable "Swift 3 @objc Inference" (only works if you migrate an existing project from Swift 3)  Mark the affected methods and properties as @objc [...]

Data structures are containers that hold data used in our programs. The efficiency of these data structures affects our software as a whole. Therefore, it is crucial that we understand the structures available for us to use and that we choose the correct ones for our various tasks. This is the first part of a two-part series on data structures in Swift. In this tutorial, we’re going to talk about generics and the built-in Swift collection types. In the second part, we’ll take a look at some of the most popular data structures and how they can be implemented in Swift. [...]
