CaseIterable is one of my favorite features in Swift 4.2. Despite being a simple protocol, it solves the common problem (that I personally faced many times) of needing access to an array containing all the cases of a certain enum.

Swift 4.2 comes with a lastIndex(of:) method. I explore how one might implement this method manually and why this is a good exercise to understand the standard library’s collection design.

Swift places a lot of emphasis on static typing, but it also supports rich metadata about types, which allows code to inspect and manipulate arbitrary values at runtime. This is exposed to Swift programmers through the Mirror API. One might wonder, how does…

Conditional Compilation along with Active Compilation Conditions is a way to alter the app’s behavior depending on the build configuration. In this article, I’ll show why these kinds of conditional blocks shouldn’t be used directly in the source code of libraries…

In this step-by-step tutorial you'll build a real-time iOS chat app, utilizing Swift and Scaledrone for real-time communication.

The debate of whether to create UI in Storyboard or Code has become so old now, there will always be developers on the different side justifying their view point, like: Using Storyboard can lead to complex merge conflict if there are multiple people working…

In the previous post, we have explained how to create UI elements like UILabel, UIButton etc using code. In this post, we will look into how to create Auto Layout constraint using code. This post assume you already know some basic Auto Layout knowledge. Starting…

(If you're searching for how to open specific view controller when a push notification is tapped, the answer is here ) How to make the app open a specific view controller when user tap on push notification? like when you tap the notification in twitter app…

In this article we'll build the enigma machine. We'll keep the implementation as close to the original as possible with a few modern modifications.

An entity graph of the Core Data data model used by Apple’s Photos framework on iOS.

View models attempt to make it easier to write and maintain view-specific logic, by introducing dedicated types for it. This week, let’s take a look at a few different ways that various flavors of view models can be implemented in Swift.

Ever wanted to implement a full-text search in your app? Didn't find a boolean search expression parser that works? Look no further! For the initial release ...

Although Swift does not support multiple inheritance, it offers rich API that gives possibility to simulate it. Let's take an in-depth look at multiple inheritance and its implementation in Swift.

Sometimes its faster to let Swift figure things out for you

In this tutorial, I'm going to give you some best practices that will help you safely and effectively use classes (reference types) and reference semantics in Swift. Protocol-oriented programming (POP) and value semantics are all the rage now, but a promising…
