What is SwiftUI WWDC?
Take your first deep-dive into building an app with SwiftUI. Learn about Views and how they work. From basic controls to sophisticated containers like lists and navigation stacks, SwiftUI enables the creation of great user interfaces, faster and more easily.
What’s new in Swift WWDC?
You will see improved handling of chained method calls and property accesses, a major component of Swift UI code. You’ll also find improvements for alignment of call arguments, tuple elements, collection elements that span multiple lines, and multi-line control flow.
When was SwiftUI introduced?

Swift is the powerful programming language that powers Apple’s app platforms, and it’s also the language we use for SwiftUI.
What is Objective C code?
The Objective-C language specifies a syntax for defining classes and methods, for calling methods of objects, and for dynamically extending classes and creating programming interfaces adapted to address specific problems. As a superset of the C programming language, Objective-C supports the same basic syntax as C.
