SwiftUI is the most exciting release since Apple announced Swift in 2014. It’s an immense start towards Apple’s goal of getting coding, simplifying the basics so that you can spend more time on custom features that delight your users.
Let’s check what SwiftUI is?
What is Swift UI?
SwiftUI is a user interface toolkit that is an innovative, straightforward way to build user interfaces across all Apple platforms using just one set of tools and APIs with the power of Swift. It is effortless and straightforward to read with declarative Swift syntax and also very natural to write. SwiftUI operates seamlessly with new Xcode design tools to keep in sync with the code and design perfectly. Automatic patron for Dynamic Type, Dark mode, localization, and accessibility, which implies the first line of SwiftUI code is already the most powerful code.
SwiftUI uses a declarative syntax which states what the user interface should do. For instance, you can work on that you want a list of items consisting of text fields, then specify alignment, font, and color for each field. The code is simpler and easier to read than ever before, saving you time and maintenance.
This declarative style will apply to complex concepts like animation. Append animation to almost any control and choose a collection of ready to use impacts with only a few lines of code. At the time of runtime, the system manages all of the steps that are required to create a smooth movement and even deals with the suspension to keep your app stable.
Xcode 11 incorporates intuitive new design tools that make developing interfaces with SwiftUI as simple as dragging and dropping. Working with design canvas, everything you need to edit is entirely in sync with the code in the adjoining editors. You can view the code immediately as a preview as you type and if any changes you made will affect the preview instantly in your code. Xcode recompiles the changes instantly you made and embeds them into a running version of your app, visible and editable at all times.
Drag and Drop: Systematize the elements within your user interface by simply dragging controls on the canvas, click to open an inspector to choose the font, color, alignment, and other design options, and re-arrange controls with the cursor. Many of these visual editors are also accessible within the code editor, by using the inspector to identify new modifiers for each control, even if you choose hand-coding parts of your interface. You can even drag controls from your library and drop them on the design canvas or can drop directly on the code.
Dynamic Replacement: The Swift compiler and runtime are fully enclosed throughout Xcode, so your app is steadily being built and run. The design canvas that the user sees is not just an approximation of the user interface – it’s your live app. And Xcode can interchange edited code directly in your live app with gradual replacement, a new feature in Swift.
Previews: Now you can create one or many shows of any SwiftUI views to get sample data and configure almost anything your users might see, such as large fonts, localization, or dark mode. Previews can also display you UI in any device and any orientation.
Native on all Apple Platforms
Swift UI was built on decades of experience in developing the most innovative and intuitive user interfaces in the world. Everything users love regarding Apple ecosystems, such as controls and platform-specific expertise, is beautifully manifested in the code. SwiftUI is genuinely native, so your apps directly obtain the proven technologies of each platform with a shortcode and an interactive design canvas.
