Video description

Apple’s SwiftUI is becoming one of the most popular tools for building iOS applications. It is as easy as dragging and dropping, and it uses five times less code compared to UIkit and storyboards. This course will teach you how to use SwiftUI features and declarative programming to build rich and robust applications for the Apple store.

The course starts with an introduction to SwiftUI and Swift language and gives you a tour of Xcode and Previews. Next, you will become familiar with the basic topics of SwiftUI, such as constants, variables, operators, classes, structs, properties, initializers, error handling, and stacks. Moving along, you will understand the role of text fields, state, image, and modifiers in SwiftUI. Toward the end, you will learn to build interesting applications in SwiftUI to encapsulate your learning.

By the end of this course, you will be able to build modern and reliable apps using SwiftUI that can be deployed to any Apple device.

What You Will Learn

  • Become familiar with the Xcode tool’s user interface
  • Understand the fundamentals of SwiftUI and Swift language
