Dependency injection is an essential tool when it comes to making code more testable. This week, let's take a look at a dependency injection technique that lets us enable testability without forcing us to write massive initializers or complicated dependency management code.
Are VIPER, RIBs, MVVM, VIP, or MVC suitable for a SwiftUI project?
How the MainActor attribute eliminates the need for us to manually dispatch UI updates on the main queue when using Swift 5.5’s new concurrency system.
Explaining the Dependency Injection pattern, by contrasting it with Service Locator. The choice between them is less important than the principle of separating configuration from use.
Learn how to use Resolver to implement dependency injection in your SwiftUI iOS apps to achieve easily readable and maintainable codebases.
Swift's type system is (mostly) fantastic. Its tight constraints and flexible generics allow developers to express complicated concepts in an extremely safe manner because the Swift compiler will…
This post shows two ways of achieving dependency injection in SwiftUI: using @EnvironmentObject or a View Model Factory.
Various techniques that let us define fully dynamic colors that adapt to the user’s selected color scheme, using either SwiftUI or UIKit.
We recently set about creating a framework and service for automatically generating social sharing images for repositories and other resources on GitHub.
When creating collections of objects or values in Swift, we usually use data structures provided by the standard library - such as Array, Dictionary and Set. While those three cover most use cases, sometimes creating a custom wrapper collection can enable us to make our code more predictable and less prone to errors.
The Codable protocols (Decodable and Encodable) were introduced to the Swift standard library with Swift 4.
The Codable protocols are one of the coolest recent additions to Swift. Even though it works similarly to its community counterparts like Unbox, Codable has the advantage of being powered by the compiler. One of my favorite features in Unbox was to give a context to the decoding operation. Let's take a look at how we can achieve the same with Codable and how I use to power a type-erased Decodable type.
Learn about checked continuations and converting closure and delegate-based code into async/await in Swift.
Deploying docker container as part of your continuous integration can cause your disk to fill up pretty quick. Docker does reuse the layers that did not change between deployments. But still, that last layer with you .war or .js bundle can take a few hundred megabytes. Taking into account, that you should be deploying a new version of every update of the master branch, this can take up a gigabyte every day.
Everything went smoothly until I tried to checkout. The checkout button was off screen and impossible to hit. So I investigated why this was happening and took a guess at how much this bug might cost the Olive Garden’s owners.
