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.
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.
Last week we discussed the new ShareLink view and the Transferable protocol powering it. The new Transferable protocol is useful for sharing your data from the app, but it also powers drag and drop in your app. This week we will learn how we can drag and drop data conforming to the Transferable protocol in SwiftUI.
Apple introduced a brand new CoreTransferable framework and ShareLink view in SwiftUI, allowing us to share and export content from our apps very declaratively. This week we will learn how to make data transferable and use the new ShareLink view in SwiftUI.
Today I want to continue the topic of UI testing in Swift by covering another great set of tools the XCTest framework provides us. I love UI testing and protecting the primary user flows in my app. This week we will talk about the hidden gems of the XCTest framework, which are activities and attachments.
In Swift, we can do performance testing using the XCTest framework, which is a part of the Xcode development environment. XCTest provides a comprehensive set of tools for writing, running, and analyzing unit and performance tests for Swift applications. This week we will learn how to do performance testing in Swift using the XCTest framework.
The last but not least post in the series is about accessibility. It is essential to make your app accessible to VoiceOver users. Usually, it is much harder to make your visual content accessible. Fortunately, Apple provides audio graph features allowing us to make any chart representable with sound. This week we will learn how to improve the accessibility of our graphs using the Swift Charts framework.
Last week we started the topic of the Swift Charts framework customization options using a bunch of chart view modifiers. It is a vast topic that I divide into a few small posts. This week we will discuss configuring the legend view using the new Swift Charts framework.
The Swift Charts framework became a huge topic on my blog. But I decided to continue this subject to cover everything I’ve experienced with the Charts framework. This week we will learn how to customize the Chart view using a bunch of chart view modifiers provided by the framework.
The Swift Charts framework provides excellent functionality for implementing super custom charts. This week we will learn how to handle user input with gestures to build interactive charts. The Chart type is a simple SwiftUI view, which means you can attach gestures and buttons to interact with the chart.
