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.
SwiftUI brings declarative and straightforward approach in building User Interfaces. We have List and Form components and Bindings. All of these things make SwiftUI so easy to use and very powerful. But today we are going to talk about another feature of SwiftUI, and it is Animations.
Apple finally released Xcode Beta 2 with an updated version of SwiftUI. The current version has a Form component which appeared on WWDC sessions. Today we are going to build form styled layout with SwiftUI. I want to show you a real-life example of the settings screen built with SwiftUI’s new Form component.
Last week we started a new series of posts about SwiftUI framework. Today I want to continue this topic by covering Property Wrappers provided by SwiftUI. SwiftUI gives us @State, @Binding, @ObservedObject, @EnvironmentObject, and @Environment Property Wrappers. So let’s try to understand the differences between them and when and why which one we have to use.
That is WWDC week: everybody is so excited about so many new things like SwiftUI, Dark Mode, updateable Core ML models, etc. I will try to cover all the new stuff during the upcoming weeks. Let’s start with SwiftUI. SwiftUI is an entirely new approach to building apps for the Apple ecosystem.
Last week before WWDC and everybody so excited about new features which we will have just in a few days. However, let’s keep posts related to WWDC for next week. This week we are going to talk about my favorite design pattern Delegate. Delegate is the most straightforward and powerful pattern.
Most of our apps are REST clients for some backends. During the development of this kind of apps, we want to keep it working offline. In this case, we have to cache data somewhere locally on the device to make it readable without an internet connection.
