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

  • Adding Events to the Calendar

    We’ve learned (read-events-from-the-calendar) how to read calendar events. In this post, we’ll learn how to add an event to the calendar. We’ll follow these steps: Let’s start by adding a new function, addEvent, in the EventStoreManager: (please get the code of the EventStoreManager from the previous post). In this tutorial, we’ll create an event on…

  • Read events from the calendar

    In this post, we’ll learn how to read events from the calendar in our SwiftUI application. In the next one, we’ll learn how to add an event to the calendar. For today’s events, I display only the title: We need to complete two steps: The Event Manager: First step: Import EventKit. The class is annotated…

  • Navigate Programmatically

    The classic way to navigate in a SwiftUI application is by using the NavigationStack with NavigationLink. In 99% of cases, this is sufficient. However, in some cases, we may need to navigate programmatically. How can we do that? As we can see, we use a path passed to the NavigationStack. When something is added to…

  • Localization

    When you create a successful app, you need to localize the application for users from different countries. To do that in Xcode is simple. In the File menu, choose New and then File from Template, then select the String Catalog and save the file as Localizable. Now, if you run the application, this file will…

  • Splash screen

    In this post, we’ll see an object that is present in many popular applications: the Splash Screen. With the storyboard, we have a specific object for that. In SwiftUI, the splash screen is a regular view that we can create however we want. In the example, the splash screen contains a heart that pulses for…

  • Alert

    We can display an alert using the .alert modifier. Take a look at the code: The role of the button can be: Note that using a button with .destructive is also added the default cancel button

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.
