SwiftUI is a new and powerful way to build user interfaces for Apple systems. In 2019, WWDC introduces Swift UI, which consists of Xcode. However, the professionals reveal SwiftUI as a new approach to develop user interfaces that work across all Apple platforms, replacing storyboards and XIBs. Last year, WWDC greet the new features and functions in Swift UI. So, the expectations for SwiftUI this year were always going to be high. The team delivered a tremendous array of improvements and features, including a new AsyncImage view for fetching remote pictures, swipe actions for list rows, pull to refresh, and shorter, simpler APIs for common purposes. So, in this blog, we will discuss the new features of the Swift UI 3.
What is new in SwiftUI 3?
Apple is still working on bringing SwiftUI, its declarative UI framework for Swift, up to UIKit and AppKit standards. SwiftUI received a variety of new features at WWDC 2021. The new features like async, concurrency, SF Symbols 3 with new styles, button styles, blur materials, Markdown support using Text, drawing graphics with canvas, and much more.
With these new features in the Swift UI 3, every iOS app development company can take more challenging apps for development. Apple is a firm believer in SwiftUI, having used it to create apps such as Photos, Maps, Shortcuts, Weather, Photos, Find My, and system interfaces such as Apple Pay.
Explanation About New Features found in the latest Swift UI 3
We will discuss the new features introduced in the Swift UI 3 and Xcode 13. However, Apple keeps updating the framework and brings many new factors that help in improving the functionality of the app.
SF Symbols 3
SF Symbols 3 now has 3,100 free icons, which is a big-time saver for both designers and developers. With the addition of Hierarchical and Palette rendering modes to the existing Monochrome and Multicolor rendering modes, you may personalize more than ever. Also, the use of the modifiers makes it easier to add variants like fill and circle while keeping icon names as short as possible.
SF Symbols are now easier to use, and a symbol Variant modifier is used to customize variants. Fill and outline will be platform-specific if not provided. Moreover, you can use the symbolRenderingMode modifier to adjust the rendering mode. Perhaps, you can also hire iOS developer to make your tasks easy in understanding the features of the Swift UI.
Background blur, often known as material sheets, is a great approach to make your text more readable. The material is an excellent alternative to only utilizing opacity if you have a multi-layered design with background, card, and content. It's used in the sidebar, tab bar, modals, control center, and even apps like Weather on iOS and macOS. The good news is that it is available with only one modification.
Graphics with Canvas
Canvas is an excellent alternative for producing vector graphics that don't require tracking or validation. The TimelineView can be used to generate high-quality animations. We'll learn how to use SF Symbols 3 to create icons, convert SVG code to Path, and animate a blob in a loop in this project. It's a lot of fun.
Working with async / await makes it easier to work with functions that need to wait for tasks to complete, such as an API call. Previously, completion handlers were required, which made the code difficult to comprehend and debug. Your code will be shorter and safer with concurrency, and you'll have access to the new AsyncImage and Pull to Refresh capabilities that take advantage of the new API.
You can load an image from a URL without using a third-party library with AsyncImage. It contains excellent features such as placeholders when loading and phases for handling errors. On top of that, transitions and animations are simple to use.
AWAIT / ASYNC
Without utilizing completion handlers, we may design an async function that retrieves data from an API. We must wait for the API call to complete before decoding the JSON data. We're also utilizing do/catch to deal with problems.
PULL TO REFRESH
You can use the new refreshable modifier to automatically establish the Pull to Refresh mechanism on a List whenever you need to refresh the data.
A lot of stuff nowadays is written in Markdown. It can handle links, photos, and basic text formatting like headings, bold, italic, and bullet points, among other things. It's a more user-friendly alternative to HTML, which can be hard to implement. Best of all, SwiftUI 3 now supports Markdown by simply utilizing the Text component.
The live preview isn't just for portrait mode anymore. Now, you can use a modifier to display the design in landscape and portrait mode.
Do you know it is never an easy task to create a search experience with the text field? We'll learn how to personalize the appearance while creating a search experience that includes data and search completion in this course.
Safe Area of Inset
Indeed, with this new feature in the Swift UI, you can place the content on the top of a Scrollable View. When you have a custom tab bar or nav bar, this is extremely useful for customizing the scroll area.
You can implement a complex swipe interaction that can pin, delete or favorite things in a List with just a few lines of code.
New Button Styles
SwiftUI Buttons have become a lot more potent in recent years. New roles and styling modifiers have been added.
ButtonRole allows you to specify the type of button. It accepts the following:
TextField in SwiftUI now has better keyboard management.
With iOS 15, we have a new property wrapper (@FocusState) for programmatically managing the current active fields. iOS Developers may now highlight a single text field in login and registration forms, which is beneficial.
In SwiftUI, we must attach FocusState in the focusedStated modifier to implement programmatic attention on TextField. If the FocusState is bound to the same view, it performs a Boolean check.
On the whole, we hope this article helps you understand the new features of the Swift UI3. Indeed, you can get in touch with an experienced iOS app development company that can guide you with all the features introduced in the Swift UI.
