This week I want to talk to you about modeling data layer in SwiftUI. I already finished work on my very first app, which I build entirely with SwiftUI. And now I can share with you the way of architecting model layer using store objects which I used during the development of NapBot.
This week I want to talk about the styling of views in SwiftUI. SwiftUI provides a pretty composable architecture for building your apps. Every screen in terms of SwiftUI is a function on some data which returns a view. So let’s talk today about composable and highly reusable styling options which we have in SwiftUI.
Environment is one of the unique features of SwiftUI which we didn’t have before in UIKit. Today I would like to show you all the benefits of using Environment in your apps. Let’s start with describing the idea of Environment. We already discussed it previously in “Understanding Property Wrappers in SwiftUI”, but I want to start with basics.
This week I want to show you how to use Shape API in SwiftUI. We will take a look at ready to use shapes like Circle, Capsule, Rectangle, etc. We will learn how to draw super custom shapes by using Path and GeometryReader. In the end, we will build BarChart implementation ultimately in SwiftUI.
ViewModifiers play a significant role in SwiftUI. Most of the functions called on a View are ViewModifiers. It is the primary way of modifying the view instance in SwiftUI. In this post, we will take a look at some ready to use ViewModifiers, and then we will build our own custom ViewModifier.
During app development using SwiftUI, you can see that your views are very coupled with the data flow. Views fetch and render the data, handle user input and actions, etc. By doing so many things views become very fat and we can’t reuse them across the app. Let’s take a look at a different way of decomposing views by using Container Views.
Last week we talked about Navigation in SwiftUI. This week I want to continue the topic with Modals, Alerts, ActionSheets, and Popovers. SwiftUI views have a dedicated modifiers for presenting this kind stuff. Let’s take a look at how we can use modifiers to display Modals, Alerts, ActionSheets, and Popovers.
This week I want to talk about Navigation in SwiftUI. SwiftUI provides both declarative and imperative ways of implementing navigation in your apps. Today we will cover two ways of Master-Detail navigation available in SwiftUI. We will learn how use NavigationLink, and how to do programmatic navigation in SwiftUI.
SwiftUI has a powerful and easy to use approach in building Gestures. Today we will talk about how we can use gestures in SwiftUI. We will touch special GestureState Property Wrapper which is very similar to State but works only with gestures. Finally, we will build swipeable Tinder cards as a sample project.
Last week we talked about “Animations and Transitions in SwiftUI”. But it’s time to touch the crucial aspect of every app, and it is Data Flow. All the apps have data to present or mutate. Data plays a vital role in apps using SwiftUI. Every view in SwiftUI is just a function of some state, where the state is our data.
