[]SwiftUI - How to align elements in left, center, and right within HStack? It is beginner-friendly, but it is also packed with design tricks and cool workflows about building the best UIs and interactions. The size of the spacing is determined by the integer passed in. In our case, that means that our LoginActionsView will no longer just stretch out horizontally, but itll now also move to the top of the screen. Today's article is going to focus on spacers and padding within Swift UI. The example in line 6 would align all the elements in the VStack to the left of the VStack view. Instead, they can be combined, and its important to understand which scenarios we should use each one in.

You can of course use both alignment and spacing at the same time, like this: That will align both text views horizontally to the leading edge (thats left for left to right languages), and place 20 points of vertical space between them. @State var searchText: String = "Search" var body: some View { TabView { NavigationView .

Think for a moment, if we want to present our content inside of a ScrollView, what could be the performance of our application using the standard Stacks? That will align both "SwiftUI" and "rocks" to their left edge, but they will still ultimately sit in the middle of the screen because the stack takes up only as much .

This is the result: As you can see, VStack arranges the Text (), HStack, and Zstack as a top-to-bottom list. The example in line 6 would align all the elements in the VStack to the left of the VStack view. The main advantage, as mentioned before, is that they can be loaded on demand, making the lazy stacks the typical go-to type of views when using dynamic content that needs to be scrolled. Update Policy So, rather than using HStack and VStack directly as container views, we can instead use them as Layout-conforming instances that are wrapped using the AnyLayout type like this: The above works since both HStack and VStack directly conform to the new Layout protocol when their Content type is EmptyView (which is the case when we dont pass any content closure to such a stack), as we can see if we take a peak at SwiftUIs public interface: Note that, due to a regression, the above conditional conformance was omitted from Xcode 14 beta 3. By the way this was not intentional, question was posted about 2 year ago.

As you can see, these are both very powerful pieces of code to know and understand when building out complex user interfaces with Swift UI. The best process to begin this without overwhelming your brain is to break down the user interface into small parts. One way to do that would be to use a GeometryReader to measure the currently available space, and based on whether the width of that space is larger than its height, we render our content using either an HStack or a VStack. UPDATE: So apparently I fixed this problem by adding a VStack inbetween ScrollView and ForEach, and estting the spacing to 0.
