A little extra clarity goes a long way

The Swift 5 release enables runtime checking of “Exclusive Access to
Memory” by default in Release builds, further enhancing Swift’s
capabilities as a safe language. In Swift 4, these runtime checks were
only enabled in Debug builds. In this post, I’ll first…

Child coordinators, navigating backwards, passing data between view controllers, and more.

Swift 5 overhauls how values in string literals are interpolated, and incidentally overturned several decades’ worth of problematic programming conventions.

Thoughts about concurrency, race conditions, locks and GCD queues

Today we will talk about Pattern Matching, one of my favorite features in Swift. Pattern Matching is the act of checking a given sequence of tokens for the presence of the constituents of some pattern. Swift has a particular keyword for applying Pattern Matching:…

There are very few certainties in app development, but one is that once your app is released it will change in unexpected ways. And no matter how flexible your architecture is, inevitably one of those changes will be a breaking change

I guess you already have heard of Dependency Injection. Dependency injection (DI) is a software design pattern that implements Inversion of Control for resolving dependencies.

Integrate SwiftLint reports, automate code reviews and save time. An overview of the most valuable Danger plugins for Swift, iOS and Mac projects.

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…

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.

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…

With test driven development you can write high quality software in small shippable steps. Here's how to get started.

There are plenty of discussions on the Internet about using third-party dependencies in your apps. The first part of developers suggest ignoring the usage of libraries and write all the code yourself. The second part recommends using third-party dependencies…

How to write safer localization code and save time by getting less distracted from your actual code writing task in Xcode.

Regular expressions are a powerful tool for working with text, but it’s often a mystery how to use them in Swift.
