Recently I have been fascinated with the fact many people, especially indie dev have started to think about accessibility for their application. However, there are still fewer resources on how do we kick off our journey in Accessibility with a more real-world use case that we can adapt. In this article, I would like to explain how do we utilize and incorporate the most basic Accessibility topics into our codebase, which is accessibilityId.
While I was looking at my twitter for inspiration, a tweet from Sean Allen caught my eyes. He made an amazing calendar component with a drag and drop capabilities of its item. I look up the possibilities of using the native SwiftUI approach without any UIKit hack or workaround to do so. In this article, I will explain step by step as well a brief explanation of the API I used to make the calendar view in SwiftUI.
VIPER is one of the hottest architectures back then because of its separation of layers that isolated between each other which is also debatable. Some argue that VIPER is over-engineer and an overkill architecture, some argue that VIPER causes too many boilerplates of code and some argue that VIPER is one of the best architecture for iOS Development. All of these opinions are valid, we definitely can use VIPER depends on how complex is our project and other undefined constraints.
Apparently, even if SwiftUI 2.0 has powerful enough for production code, but sometimes they are still lacking documentation for a simple component like PagingView. As your information, there is now a native equivalent of UIPageViewController in SwiftUI 2.0 which is adding the .tabViewStyle modifier to TabView and pass PageTabViewStyle
Let me go through step by step.
We will need to wrap our view with the GeometryReader in order to get the parent relative size position for configuring the onboarding view frame.
Combine, is a new framework introduced by Apple since SwiftUI 1.0 back then in 2019. The architecture behind the scene itself is adopting the system of FRP (Functional Reactive Programming) which takes computation as their main computation of process combine with the propagation of data through the stream of the function. In this tutorial, I would like to explain how Combine can make your job done quicker than ever compare with the conventional way of code.
SwiftUI is very powerful for building an interactive UI at a fast pace. However, there are a couple of limitations still there such as some native API from UIKit like MKMapView from MapKit or search bar and other UIKit API. I will provide a tutorial for making a MapView in SwiftUI by using UIViewRepresentable as well as putting callback to the SwiftUI if we have clicked the annotation.
Some quick knowledge about several items below:
SwiftUI is a really powerful language since it was born in 2019. In 2020 (WWDC) Apple did announce a lot of improvement on SwiftUI. However, there is rarely a topic discussed good practices on how to do we able to implement protocol-oriented programming in SwiftUI. There are a lot of articles out there however I guarantee to cover that in 5 minutes of your time. This article is suitable for those who are just starting to learn about iOS Programming !
