Let's add its SwiftUI cell view code into a new file LeadCellView as: struct LeadCellView: View. Note: PreviewProvider is mandatory to see an instant preview in the preview pane. When we click Create Preview from the preview pane, this is how it generates code on its own: As we build the project, the screen should look like this, with a preview pane on the right:

Step 3: We need to add the SwiftUI code now.įor this, we use import SwiftUI. Set the HostingViewController's class to the view controller we just created, namely HostingViewController. Step 2: Drag a Hosting View Controller from the Object Library onto the storyboard Note: You won't get UIHostingController in the Subclass dropdown, you will have to add it manually. I have named it HostingViewController like the image below: Step 1: Create a view controller as a subclass of UIHostingController. Here we will be discussing a simple way to use SwiftUI into our existing project, which already consists of a storyboard. Up until now we've been able to use combinations of VStack and HStack to achieve similar results, but known deep down that there's a better way SwiftUI 2 introduces LazyHGrid and LazyVGrid to bridge the gap between stacks in SwiftUI and UICollectionView in UIKit, these grids will dynamically resize your SwiftUI views based on the layout.

Automatic support for Dynamic Type and Localizationīut wait, can we start using it right away in our current application along with storyboards? The answer is YES!.

Declarative syntax - Simpler code, easier to read and understand.

Gives us an instant, real-time preview(The best thing I like about SwiftUI!).

These are the main reasons why I prefer using SwiftUI over storyboards: With a declarative Swift syntax that’s easy to read and natural to write, SwiftUI works seamlessly with new Xcode design tools to keep your code and design perfectly in sync.' But why should I transition to SwiftUI? What is SwiftUI?Īccording to the official Apple developer site, 'SwiftUI is an innovative, exceptionally simple way to build user interfaces across all Apple platforms with the power of Swift. Ever since the announcement, everyone has been inquisitive about playing with SwiftUI. SwiftUI has been a significant change that came in much after storyboards in Xcode. Instead, we can start implementing new ways in conjunction with the current one, thus making it interoperable. That doesn't mean we need to rewrite or redesign what we have developed in the past.

Eventually, we all need to learn, transition and evolve.

In the current era, it is tough to remain stuck in the same way of doing things. 4 min read Integrate SwiftUI in the existing project(Storyboard).
