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…

When testing delegates, we are asserting rigid implementation details. Here's a way to make those tests more flexible.

After some times creating different iOS apps following an MVVM pattern, I’m often not sure how to implement the navigation. If the View handles the rendering and user’s interactions and the ViewModel the service or business logic, where does the navigation…

I was removing quite a few protocols and classes lately. Turns out, I like what's left. I relied on classes for example because they can be subclassed ...

MVC is the app architecture that Apple recommends to the developers when developing iOS application. It provides clear separation between…

Tinder - we all know that dating app where you can just reject or accept someone by swiping right or left. BAM! The whole card swiping idea is now used in tons of apps. It’s a way to show data if you have grown tired of using table views and collection views.…

Create applications & automate workflows with Appy Pie’s workflow automation & no-code development platform.

When deadlines are tight and the product faces considerable changes, it's common for developers to make concessions in the project's quality to make sure it gets shipped in time. This leads to release anxiety - that stressful feeling where you're unsure if…

How do you compare two version strings in Swift? For example, how can I check if version “2.2.5” is higher than “2.0.3” or that a version is at least “1.8.5”? As long as your version strings follow a consistent format it turns out to be not too hard.

In this article you'll learn how to format your code with SwiftFormat. A popular little library for formatting swift code.

In this tutorial, you’ll learn how to use GitHub, Travis, Jenkins and fastlane to make Continuous Integration part of your daily workflow.

Conceptually, I like asset catalogs. It makes sense to group images and metadata together, with a visual way to edit it all in Xcode.

Last week we touched the entirely new topic on my blog. This week we will continue the Unit Testing subject. One of the smells of a good architecture is the ability to cover it with Unit Tests. Today we will talk about extracting Presentation logic into testable…

An exploration of error handling in Swift: then, now, and soon.

Good architectures result in apps that perform well and are easy to maintain. Here is our feedback on functional reactive architecture!

One major benefit of Swift’s protocol-oriented design is that it enables us to write generic code that’s compatible with a wide range of types. Let’s take a look at how we can wrap the Sequence protocol in generic containers, that’ll let us encapsulate various…
