Recently, I wanted to access the workouts tracked and saved on my Apple Watch with a Swift application, as I needed the coordinates of every workout that I recorded so far. Initially, I wasn't sure whether this type of data was accessible at all, but luckily, everything was

Real-time features on the web are usually built around WebSockets, bi-directional data channels, which send messages back and forth. While there are a lot of clients for testing network requests, there are limited solutions for observing WebSockets over time. Today I'm introducing a new application I've

With WWDC21 being kicked off officially, all technologies have received major upgrades, including SwiftUI. One of the bigger changes, a new view has been added to solve a complex problem SwiftUI developers faced until now: Loading remote images. The new AsyncImage view allows to load and display any arbitrary image

Continuing the long-standing tradition, together with this year's WWDC, Apple has announced the Swift Student Challenge. To participate, you'll have to prepare an interactive Swift playground (that can be experienced in three minutes). I participated in this year's challenge and wrote up my experience

This post deals with the internals of my newly-released navigation library for SwiftUI, Stapel. In my previous post, we took a deep dive into how mobile application navigation usually works. We saw that views are built in layers, pushed onto a virtual stack once a user taps a specific button,

This post deals with the internals of my newly-released navigation library for SwiftUI, Stapel. Today's mobile applications offer a lot of different features, but in most cases, they're built on a simple principle: You're viewing a certain view and by tapping buttons, links, or

Programmatic navigation can be quite hard to build in SwiftUI, requiring you to manage a lot of state internally, figuring out how to nest views correctly so push behaviour works as expected, it's not a lot of fun. I'm excited to announce that I've
SwiftUI
Imagine you're building a messaging app where you can invite people with a link. Normally, links are opened in Safari, which doesn't give your users the seamless experience you might hope for. Luckily, you can implement a feature called universal links (often referred to as deep

When developing applications with SwiftUI, you can utilize a wide range of great tools to get instant visual feedback, previews on multiple devices, and even different device types, all in real-time. In my previous post, I emphasized the benefits of building self-contained, reusable, and testable views. When you're
SwiftUI
Views are the atomic building blocks of SwiftUI. You combine views to create different components which then add up to screens of your application. Since you most likely want to display dynamic data, your views will have different requirements in terms of data they receive, and the logic they expose.

The process of breaking into a new field is always challenging. I've often felt as if I were being held back by an entry barrier that prevents me from progressing, like a lower boundary. Being persistent, repeating, and learning are the only way to break through this barrier.
