My preference is not to use it because Apple doesn’t use it in the template. 2)Click Next Add the Product Name and change the interference as SwiftUI Chose the Language Swift 3) Click on the ContentView as Shown in Image Use List as.

If you wanted to, you can still prepend line 3 by adding return to the front, but Swift 5.1 doesn’t care if the keyword return is used or not. With opaque types and Swift 5.1, we do not need to specify the return keyword. Please note that I speak about returning a view. Thankfully, there are types, such as stacks, that allow us to embed other views within the stack and then return the stack as a single view, thus, conforming to the View protocol and satisfying the opaque result type. LazyVStack’s behaviour is similar to VStack’s with the exception of laziness.In many instances, lazy means if you do not see it on your screen, it is not being loaded. Don't know if is there a problem with using lazyviews with scrollview. Does this make sense I know List actually uses reusable cells that increases the overall performance. So, I consider to use lazy stackviews that populated by foreach loop inside a scrollview. View builder is limited to only ten child views. As you can see, the scroll view frame and scroll indicator are push to the edge. Finally, the ZStack in line 11 creates a layout for the child views. Similarly, the VStack in line 6 creates a vertical layout for child views/elements to appear in a vertical format. The HStack in line 1 creates a layout for the child views/elements to appear next to one another horizontally. We set one of the scroll view children to occupy maximum width, making the scroll view occupy the same space. There are three main types of Stacks shown above.

Even better, we can use Stack spacing and Spacers in combination to bring more flexibility in the arrangement of views. List has lot of limitations right now, it is not as flexible as tableview in uikit. If you want to change that, you can use the frame () modifier. We can also add spacing inside Stacks and align the views in a certain manner.

To make all the views equally spaced, add a Spacer () between each of them. We’ve removed it from the project for convenience as well. Imagine if our view, ie… the part that the user interacts with on screen, was only able to show one Text field or perhaps one button, then interfaces would be incredibly boring. At WWDC 2020, Apple introduced the LazyVStack.In my opinion, it is an improved version of VStack due to its advantage in performance. The first Spacer pushes the Image to the top of the screen. An opaque result type means that we must return one, and only one, of the specified type, in this case something that conforms to the “View” protocol. This is a new feature added added in Swift 5.1. Each of them have views inside, like Text () and Image (). However, since ForEach reuses the views that it creates in order to optimize performance (just like other list-based views, like UITableView and UICollectionView, do), it requires us to.

Instead, you use things like HStack, VStack, ZStack, Groups, Lists, and more. SwiftUI’s ForEach type enables us to create a series of views by transforming each element within a collection. In the example below, you will see a combination of VStack, HStack, and ZStack. Theres no AutoLayout or related problems. The word “some” means that we are dealing with an opaque result type. A good way to achieve this is using a combination of Stacks. In this series, I am going to teach you everything you need to know about List views, from simple lists, styling lists and their items, displaying collections of data in list views, implementing actions on lists and individual list items, to building nested outlines and implementing three-column drill-down navigation UIs that work across iOS, iPadOS, watchOS, and macOS.When you create a SwiftUI view, the protocol defines that we need to return “some View”. SwiftUI makes it particularly easy to build list views: it just takes three lines to create a simple list! At the same time, SwiftUI’s List view is extremely powerful and versatile, so it pays off to get to know it in a little bit more detail. List views are probably one of the most important UI structures in iOS apps, and you’ll be hard-pressed to find an app that doesn’t use some sort of list.
