Mastering SwiftUI: Your Guide to Building Beautiful, Intuitive Apps.

  • REST – Episode III – Obsevation Framework

    In this post, we’ll take a look at the Observation framework. The idea is that this framework will replace Combine, so for those starting to develop on iOS now, it’s better to start with it – it’s the future. Let’s see how it works using the structures from the first episode SwiftUI and REST (Episode…

  • SwiftUI – Episode II – POST and Authentication

    In this post, we’ll learn how to perform POST requests and use a bearer token to access REST APIs that require authentication. At the end of the post, you’ll find a link to the GitHub project, which includes the code for the mobile application as well as a simple server for testing purposes. Post First,…

  • Rest – Episode I° – Get

    In this episode, we will see how to implement a GET request. In the next one, we’ll explore how to make a POST request, and in the last one, we’ll examine different solutions. Suppose we want to search for books using the Google Books API: https://www.googleapis.com/books/v1/volumes?q=intitle:your-word. The idea is to write the search text in…

  • Share data in an application

    Many blog posts are responses to my students’ questions, and this one is no different. Often, my students need to build fast prototypes without saving permanent data and want to avoid writing complicated code with Core Data or the newer SwiftData. They frequently ask, “How can we share data across the application without passing it…

  • SwiftData – Episode III°

    In this episode about SwiftData we’ll learn: Before we start, I advise you to review the previous episodes (SwiftData – Episode I°- Introduction and SwiftData – Episode – II° – Delete/) Edit Data First of all, we will create the view to edit a ProjectItem: A part from the variable used to dismiss the sheet…

  • SwiftData – Episode II° – Delete

    In this episode, we’ll learn how to delete data. Let’s start with deletion in the projects (I advise you to take a look at the previous episode because I will start from that code). The first step is to ensure that when we delete a project, we also delete all the pomodoros for that project…

This is how it all started…

I started coding in the ’80s when I was a teenager with a Commodore Amiga 500 (which I bought 50% with my brother after a summer of work in the fields). My first programming language was AmigaBasic, but I soon moved on to C. At university, I discovered Linux, and it was love at first sight (1996). In the meantime, I became interested in the OpenSource world and the Qt framework (which has played an important role in my professional life). Along the way, I also worked with other technologies, but my background is in embedded engineering, so I transitioned to system programming and mobile development.

Mobile development is a key focus of this blog. I contributed to the Maemo, MeeGo, Mer, and SailfishOS projects. After that, I moved on to Android and later iOS. Since 2017, I’ve been a mentor at the local university for the Apple Foundation Program, a four-week full-immersion course where students learn how to create simple(?) mobile applications for iOS (as well as for Apple Watch and Apple TV). After writing nearly a hundred posts about SwiftUI, I decided to collect them all in one place, here, where I’ll create a path to develop iOS applications, following more or less what I teach my students, along with other insights.
