MainActor usage in Swift explained to dispatch to the main thread
MainActor is a new attribute introduced in Swift 5.5 as a global actor providing an executor which performs its tasks on the main thread. When building apps, it’s essential to perform UI updating tasks on the main thread, which can sometimes be challenging when using several background threads. Using the @MainActor attribute will help ensure …
Optimizing your app for Network Reachability
Network Reachability is a vital aspect of apps that use some networking capabilities. Your users won’t always have a good internet connection, so optimizing your app for bad networking conditions is essential. We can leverage several techniques to optimize our app accordingly, but it’s essential to be aware of common mistakes when you do. After …
Deeplink URL handling in SwiftUI
Deeplinks allow you to open your app and navigate into a specific location right after launch. An example could be deep linking to a recipe or movie based on the tapped link. You can determine the destination page based on the metadata provided by the URL. You can use a view modifier in SwiftUI or …
Network Extension Debugging on macOS
A Network Extension on macOS allows you to create content filters, DNS proxies, and more. They integrate nicely into the system settings and are often used for applications like firewalls and VPN services.

The errors often come with an error code that doesn’t have a description, leaving you behind with unclear directions on solving the issue. I’ve been running into these errors quite often, at which I opened several …
View Composition using ViewModifiers in SwiftUI
View Composition allows you to create reusable components to create enriched views. You can extract logic into reusable components using the ViewModifier protocol in SwiftUI and set up your code for reusability. I’ve been developing a set of view modifiers in RocketSim to enable TextField customizations. Combining all modifiers results in the most advanced TextField, …

While developing apps, spending your time on the most impactful features is essential. While the definition of impactful divers it’s certainly driven by what your users want to see in your app. With …
Detached Tasks in Swift explained with code examples
Detached tasks allow you to create a new top-level task and disconnect from the current structured concurrency context. You could argue that using them results in unstructured concurrency since you’re disconnecting potentially relevant tasks. While it sounds terrible to disconnect from structured concurrency, there are still examples of use cases in which you can benefit …
