To make it look real, I just wrote a code that randomly generate some ID. Now you are getting ready to get your hands dirty and start coding. content A view builder that creates the content of this stack. spacing The distance between adjacent subviews, or nil if you want the stack to choose a default distance for each pair of subviews. This guide has the same vertical screen coordinate for every child view. Bear in mind that the minimum iOS requirement is iOS14+. alignment The guide for aligning the subviews in this stack. This is the scenario, you are recently hired by a company to build an employee database and its now 2024, the minimum iOS on each iPhone device is at least iOS16+ and the requirement for this is, it shouldn’t be laggy.
The usage is similar with VStack and I took this a little further making it more interesting when playing with it. The alignment property of a VStack only applies to the horizontal alignment of the contained controls using HorizontalAlignment.

In summary, use LazyVStack if you have a huge amount of data and VStack when you have a considerable small amount of data.Ī view that arranges its children in a line that grows vertically, creating items only as needed. The class has this code by default: Step 3: We need to add the SwiftUI code now. Set the HostingViewControllers class to the view controller we just created, namely HostingViewController. Just think of it this way, if you have a huge load of data, the ideal way is to load what you see only which is what LazyVStack is doing and as you scroll, you will load the data. Step 2: Drag a Hosting View Controller from the Object Library onto the storyboard.
On the other hand, VStack is a little opposite with this, it loads everything. Lazy in many instance means if you are not you are not seeing it in your screen, it is not being loaded which in turn increases performances.
LazyVStack behaviour is similar with VStack with the exception of lazy. ZStack allows you to keep stacking your component on each other. To follow along this tutorial, you’ll need some basic knowledge in: A basic familiarity with Swift. As is to be expected, SwiftUI includes a wide range of user interface components.
You’ll learn: How to build a ZStack from scratch. User interface design is largely a matter of selecting the appropriate interface components, deciding how those views will be positioned on the screen, and then implementing navigation between the different screens and views of the app. In the recent WWDC 2020, Apple introduced an LazyVStack which in my opinion is an improved version of VStack due to its advantage in performance. In this tutorial, you’ll learn what it takes to build a ZStack in SwiftUI.
