With the introduction of SwiftUI in 2019, Apple brought a revolutionary change to the way we build iOS apps. SwiftUI is a declarative framework that makes it easier and faster to build dynamic, responsive, and visually stunning user interfaces.

Let’s explore the power of SwiftUI and how it’s changing the way we build iOS apps.

Declarative Syntax

One of the most significant benefits of SwiftUI is its declarative syntax. With SwiftUI, you declare what you want the user interface to look like, and the framework takes care of the rest. This means you don’t have to write a lot of boilerplate code to define and manipulate the user interface elements.

For example, here’s how you would create a simple text view in UIKit:

let label = UILabel()
label.text = "Hello, World!"
label.textAlignment = .center
label.textColor = .black
label.font = UIFont.systemFont(ofSize: 24)

In SwiftUI, you can create the same text view in just a few lines of code:

Text("Hello, World!")
    .font(.system(size: 24))
    .foregroundColor(.black)
    .multilineTextAlignment(.center)
