iOS Development with SwiftUI

In the course iOS development with SwiftUI from SpiralTrain, participants learn to use the programming language Swift and the declarative SwiftUI framework for the development of apps for the iPhone a

Swift Review

The course iOS Development with SwiftUI kicks off with a review of key elements of the Swift programming language. This includes the discussion of type inference, classes, structures, guards and closures.

Swift UI Architecture

Next the declarative and data driven SwiftUI syntax and the use of SwiftUI projects in XCode are discussed. Attention is also paid to the SwiftUI App and UI hierarchy, the various SwiftUI views, stacks, frames and also to event handling in Swift UI.

Data Persistence

There are several ways to store data in SwiftUI apps. Scene Storage and App Storage are treated and access to the file system of a device is discussed as well. Attention is also paid to storing data in a key value store and in a relational database such as SQLite. Lifecycle modifiers are also reviewed.

Navigation

Navigating between different screens in a SwiftUI app is also part of the program of the course. This section discusses the use of NavigationViews and NavigationLinks that can be included in List and Dynamic Lists.

Gestures

Gestures in mobile apps relate to interaction with the device through taps, clicks and swipes. The use of gestures in SwiftUI is treated as well as the combination with animations.

SwiftUI Widgets

Widgets are the visual building blocks of the user interface of a Swift UI App. Various widgets such as lists, grids, buttons, switches, tables, date pickers and maps are covered. Attention is also paid to the creation of User Defined widgets with the WidgetKit.

UI Kit Integration

Finally the course discusses how existing iOS apps based on the UI kit architecture can be integrated with the SwiftUI architecture. The role of UIViewControllers and Storyboards is covered here.

Audience Course iOS Development with SwiftUI

The course iOS Development with SwiftUI is intended for developers who want to use the declarative SwiftUI framework to develop apps for iPhone and iPad.
