In addition to animating changes made to animatable properties of views, SwiftUI also allows you to specify your own animation, such as moving views or rotating views. Here, you learn how to rotate views in two dimensions in SwiftUI. Rotating in 2D To perform rotation in two dimensions in SwiftUI, use the rotationEffect() modifier.

To animate a view in SwiftUI, apply the animation() modifier on it. SwiftUI animates any changes made to animatable properties of a view. For example, the various properties of a view in SwiftUI — such as its color, opacity, rotation, size, and other properties — are all animatable. As usual, the best way to understand this concept is to use an example.

Did you know you can use UIKit in SwiftUI? It’s true! When you develop iOS apps using Storyboard in Xcode, you use the UIKit for all UI matters. UIKit is the framework that forms the core components of all iOS applications. Among all the classes in the UIKit, view and view controllers are the most commonly used classes.

One important feature in Swift is closure. Closures are self-contained blocks of code that can be passed to functions to be executed as independent code units. Think of a closure as a function without a name. In fact, functions are actually special cases of closures. ©Shutterstock/NDAB CreativitySwift offers various ways to optimize closures so that they’re brief and succinct.

Are you ready to build iOS apps using an innovative and intuitive user interface? Then, SwiftUI is for you! But before you dive in, you’ll need to know about Swift functions. Here’s a quick intro. ©Shutterstock/baranqIn Swift, a function is defined using the func keyword, like this: func doSomething() { print("doSomething") } The preceding code snippet defines a function called doSomething.

SwiftUI makes creating your iOS applications easy and efficient. However, there are neat tricks that are not so obvious.

Localizing your iOS app allows you to target it for the international market. A common task in localization involves translating the user interface (UI) of your app to display strings in the local language. SwiftUI makes localization straightforward. But you need to perform a few steps to get it set up localization in SwiftUI: Go to the Info page of your project and select the project name.

Swift is a type-safe language, which means that the programming language makes it clear to you the types of values your code is working with. The following article discusses how to declare constants and variables and how to work with strings and comments when programming with Swift. Swift constants In Swift, you create a constant using the let keyword: let radius = 3.
