Segmented Control in SwiftUI
Another option we can use for horizontal navigation is the segmented control. In this post, we’ll learn: Create the segment control Let’s start by creating a segment control that allows choosing from the days of the week: So, the Segment Control is created by using a Picker and setting its style to segmented. If you…

Sheet
An important element in iOS is the Sheet. In this post, we will cover: In this example i use this image Unsplash Creating a Non-Full-Screen Sheet Begin by creating the project and adding the image to the assets. I’ve renamed the image to background. First, we add a ‘plus’ button to the toolbar. When this…

Navigation Title and Toolbar
We can configure the navigation bar by adding the title and defining how to display it. To achieve this: It is also possible to set the title at the top and center it by adding the display mode like this: The default display mode is automatic, which means the title is displayed large and aligned…

NavigationStack & TabView
Often, or perhaps always, we have a hierarchical navigation (NavigationStack) combined with horizontal navigation (TabView). We can merge them in two main ways. Let’s see how to merge them using the first approach (which I don’t recommend because we lose the TabView). First way We have declared a NavigationStack that contains the TabView. Now, within…

TabView
One of the changes I like in SwiftUI, released with Xcode 16, is the new way to write a TabView. Now we can write: To have: We can define a View to use in the first tab, for example. Feel free to customize the others as you like. Now in the Tab: We can also…

Navigation
The iOS application uses two main components to allow navigation: NavigationStack and TabView. In this post, we’ll focus on the first one. For simplicity, we’ll start by implementing navigation, moving from one view to an empty view. The main component is the NavigationStack. You should define only one NavigationStack in the root view of your…

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