WIth the introduction of Xcode 15 beta and its corresponding beta OSses (I would say iOS 17 beta, but of course we also get macOS, iPadOS, and other betas…) Apple has introduced new state mangement tools for SwiftUI. One of these new tools is the @Bindable property wrapper. In an earlier post I explained that […]

With iOS 17, macOS Sonoma and the other OSses from this year’s generation, Apple has made a couple of changes to how we work with data in SwiftUI. Mainly, Apple has introduced a Combine-free version of @ObservableObject and @StateObject which takes the shape of the @Observable macro which is part of a new package called […]

With Swift 5.9 and Xcode 15, we have the ability to leverage Macros in Swift. Macros can either be written with at @ prefix or with a # prefix, depending on where they’re being used. If you want to see some examples of Macros in Swift, you can take a look at this repository that […]

As a developer, joining a new project or company is often a daunting and scary task. You have to get aquatinted with not just a whole new team of people, but you also have to familiarize yourself with an entirely new codebase that might use new naming conventions, follows patterns that you’re not familiar with, […]

When you just start out with learning Swift Concurrency you’ll find that there are several ways to create new tasks. Roughly speaking, you can make one of three tasks in Swift: Unstructured Tasks Detached Tasks Child Tasks While it’s true that a detached task is also unstructured, in this post I will refer to the […]

Swift’s async await syntax heavily relies on a concept called Structured Concurrency. Structured concurrency describes the relationship between tasks that perform concurrent work. Specifically, it defines the relationship between parent and child tasks in Swift. Structured Concurrency finds its roots in the fork join model which is a model that stems from the sixties. In […]

Every once in a while I find myself writing about or experimenting with web sockets. As an iOS developer, I’m not terribly familiar with setting up and programming servers that leverage web sockets beyond some toy projects in college. Regardless, I figured that since I have some posts that cover web sockets on my blog, […]

In iOS 13, we gained the ability to easily send and receive data using web sockets through URLSession. With async/await, we gained the ability to fetch data from servers using the await keyword and we can iterate over asynchronous sequences using async for loops. We can even read data from a URL one line at […]

In an earlier post, I wrote about different ways that you can bridge your existing asynchronous code over to Swift’s new Concurrency system that leverages async / await. The mechanisms shown there work great for code where your code produces a single result that can be modeled as a single value. Since writing this post […]

Sometimes in SwiftUI apps I’ll find that I have a model with an optional value that I’d like to pass to a view that requires a non optional value. This is especially the case when you’re using Core Data in your SwiftUI apps and use auto-generated models. These models will usually include optional values for […]
