Concurrent code can come in many different shapes and forms. Depending on what we’re trying to achieve, the abstraction that’ll prove to be the best fit might vary quite a lot from use case to use case. One such abstraction is Tasks, and this week, let’s…

Strings are everywhere. We all use strings everyday. In Swift `String` is a very powerful type. One of the features it had available since the beginning is the string interpolation. With it we can embed any Swift expression inside the string literal instead…

The release of Swift 5 is coming with Xcode 10.2 and brings some updates to the String API in the standard library. Here’s a look at the new character properties that allow you to test for a number of useful Unicode properties.

Reflection is a common programming language feature that enables us to inspect, and work with, the members of a type — dynamically, at runtime. That may seem at odds with Swift’s heavy focus on compile-time validation — but this week, let’s take a look at…

One way to make a code base easier to navigate, while still maintaining a solid overall structure, is to inline functionality whenever two pieces of code are heavily related. This week, let’s take a look at how that can be done using inline types and functions…

One really elegant aspect of Swift’s design is how it manages to hide much of its power behind much simpler programming constructs. Pattern matching is one source of that power, especially considering how it’s integrated into many different aspects of the…

In this article we will be generating strong passwords with AutoFill and store them in the keychain so they can easily be used when logging in.

The UserDefaults API can at first glance appear to be somewhat limited. However, it turns out that the power of UserDefaults extends far beyond simply storing and loading basic value types. This week, let’s take a look at what some of that power comes from…

Unwind segues in iOS can be quite confusing. Unlike their forward counterpart, they are based on a more complicated mechanism and different rules. That usually complicates their setup. Moreover, many wonder why you should use an unwind segue when you can…

There might be occassion that your app got launched by user tapping push notification in the control center. Sometimes we might want to do a certain action if the app is launched from push notification, say move to a certain view controller or call a certain…

Learn how to create a pod from scratch and utilize Travis and Codecov to make the pod robust.

Weak vs strong vs unowned – know the difference in closures

ServerSide.swift - the conference for server-side Swift developers

RxSwift uses quite a lot of operators utilizing reactive patterns. It is a core part where its magic happens. The Clarke’s third law says: Any sufficiently advanced technology is indistinguishable from magic. In the previous article, we found out the basic…

If you are struggling with massive view controllers you are likely to come across the suggestion to use container view controllers. A parent view controller splits a user interface into several, simpler, child view controllers. You add the root views of each…

When writing any kind of automated tests, it can sometimes be tricky to achieve a balance between making tests run efficiently and predictably, while still exercising the right code paths under realistic conditions. This week, let’s take a look at one way…

Christmas has always been one of my favourite times of the year. For me, Christmas is a season that brings so much love, laughter…
