I just uploaded a video on YouTube that teaches protocol oriented programming. You can check it out here:
Conforming to Sequence Protocol in Swift 4 to Create a Byte Data Structure
I just uploaded a video on YouTube that demonstrates how you can create a data structure, called Byte, that can hold 8 bits of data, from scratch, using Sequence. Happy watching!
ScrollView + UILabel (Scrollable label with Auto Layout)
I just created a tutorial on YouTube that shows you how you can create scrollable labels
Swift Weekly – Issue 10 – The Swift Runtime (Part 8) – Switch Statement
I was thinking of writing an article this week about the switch statement but i almost fell asleep half way through the article. that’s super boring. to write it even! so I thought I’ll do something more exciting and that is looking at how theswitch statement and its complementary case statement works.

Swift Weekly is today’s most trending Swift repo on GitHub
Swift-Weekly is gaining some stance on GitHub really. i didn’t think this hobby project of mine could get so many people excited about Swift. Check it out here.
Swift Weekly – Issue 07 – The Swift Runtime (Part 5) – Operators
I thought I’d write about operators a bit in this issue. I don’t like to teach how operators work, but rather show you some cool things that we can do with operators. but then again, many websites do that already. you can just search online and find hundreds, if not thousands of blogs/websites that can teach you how to use operators and how to create your own in Swift. so how can i be different and offer something else? well, we will talk about operators in this issue and how to write your own, but, i will also show you how custom operators are compiled by the Swift compiler.

Swift Weekly – Issue 06 – The Swift Runtime (Part 4) – Generics
Generics are pretty cool. They let us do complicated stuff that many programmers don’t want to deal with sometimes and want to stick with traditional means of achieving the same goals but using basic ideas in OOP. In this edition of Swift Weekly, I won’t teach you about generics eventhough you may just see the examples and learn generics anyways. What I will teach you however is how generics are compiled at the assembly level buy the Swift compiler.
I am going to use the release version of the code to make sure the output assembly is as optimized as possible so that the optimization level is set to -O in the output when your Swift files are being compiled. Also my swift -versionshows this:
Swift version 1.1 (swift-600.0.54.20)
Target: x86_64-apple-darwin14.0.0
I am using the latest beta of Xcode, aka Version 6.2 (6C86e). Let’s get started.
Note: I am going to get rid of some of the assembly code that is not relevant to the main point of this week’s objective.

Swift Weekly – Issue 05 – The Builder Pattern and Fluent Interface
A few weeks ago I started checking out some Wikipedia articles about various s/e design patterns and came across theBuilder pattern which is a Creational GoF pattern. Then as you know, I cannot just read one article in one sitting. I have to click every link that the article leads to, so I stumbled upon the article about Fluent Interfaces and I could then see the possibilities.
Note: Fluent Interfaces have nothing to do with IB or a visual interface that is displayed on the screen at all. Fluent interfaces are the way that we can write our software to ensure they are… well… fluent. Read on to understand how this works.
I don’t think fluent interfaces are the same as the builder pattern. I don’t really think fluent interface is actually a pattern at all. I believe that fluent interfaces are a concept, and a kick ass one at that. I think mixing fluent interfaces and the builder pattern will allos us to build Swift classes that are amazingly simple to use, instead of the classic OOP designs that we see on pretty much every Apple class these days. I wish Apple could read this article and (ehem), just update their iOS SDK classes for instance to use fluent interfaces and the builder pattern.
If you want to write your Swift apps in the most kick ass way, continue reading. I think this article will help you a lot not only in learning more about Swift, but also writing some really crazy code that will make your life and those around you much easier.
