What is new in SwiftUI after WWDC 23

WWDC 23 is here, so many things have changed and been added to the SwiftUI framework. In this post, you can find the summary of the most significant SwiftUI features available in the 5th iteration of the framework.

Mastering Swift Foundation Formatter API. Basics

One of the significant additions to the Swift Foundation was the new Formatter API. After almost two years of using it, I apply it in every project, and even more, I try to build my data formatting logic around this API. Today we will learn how to use the new Swift Foundation Formatter APIs.

Dynamic member lookup in Swift

One of my favorite features of the Swift Language is the dynamic member lookup. We don’t use it very often, but it improves the API of the provided type significantly by improving the way we access the data of the particular type.

API availability in Swift

WWDC is coming pretty soon, and we are going to use a bunch of new APIs. But how to use new APIs available only for the latest version of iOS? This week we will learn about availability conditions in Swift.

File importing and exporting in SwiftUI

A few weeks ago, we talked about photo and video picking in SwiftUI. Today we will continue the topic and learn how to import and export files in SwiftUI views. Fortunately, it is straightforward to do with the help of new fileImporter and fileExporter view modifiers.

The power of overlays in SwiftUI

An overlay is a view drawing on top of another view. And today, we will talk about two interesting use cases of using overlays in SwiftUI. One of them allows us to keep the structural identity of the view, and another one becomes very handy whenever you build custom navigation transitions.

PhotosPicker in SwiftUI

Nowadays, many frameworks Xcode provides us contain SwiftUI views, including the PhotosUI framework. The PhotosUI framework provides the PhotosPicker button, allowing us to offer photo-picking functionality in our apps quickly. This week we will learn how to use the PhotosPicker view in SwiftUI.

ImageRenderer in SwiftUI

I work on a medical app where the user needs to export health data rendered using the Swift Charts framework. It was straightforward to achieve by leveraging the power of the new ImageRenderer type. This week we will learn how to use the ImageRenderer type to export SwiftUI view as image or PDF.

Mastering Canvas in SwiftUI

You can draw 2D graphics in SwiftUI using Shape API, but in the end, the framework converts all the shapes into SwiftUI views and render them. This approach has its pros and cons. Fortunately, we can draw rich 2D graphics without combining multiple shapes. This week we will learn how to use Canvas view in SwiftUI.
