![]() ![]() ![]() trailing – align views to the right (LTR) center – align them in the middle (default) center – align subviews in the middle (default) bottom – stick ’em to the bottom of the stack top – “stick” views to the top of the stack You’ve got a few options to align VStack and HStack: The width and height are the same as the size of the largest subview in the stack. It’s counter-intuitive, but VStacks are aligned on the horizontal axis, and HStacks on the vertical axis. The value’s type is Double, but you can also provide integer values. The spacing parameter determines the amount of space or “margins” between subviews in a stack, in points. In the initializer functions, both the alignment and spacing parameters are optional – you can include both, either or none. ![]() The alignment parameter takes values from the HorizontalAlignment and VerticalAlignment structs, for VStack and HStack respectively. When creating a VStack or HStack, you can provide a value for the alignment and/or spacing parameters. Because stacks follow a box-like layout system, it’s essential that you can position the stack’s subviews as you see fit. Stacks in SwiftUI have 2 important attributes: their alignment and spacing. You can learn more about modifiers here: Create UIs with Views and Modifiers in SwiftUI Stack Layout with Alignment and Spacing #SWIFTUI VSTACK ALIGNMENT CODE#The first view in the ZStack is shown at the back of the stack, behind the others.Īuthor’s Note: I’ve omitted a few modifiers in the ZStack code example, for brevity. Comparing the SwiftUI code and the screenshot, you can infer that the order is back-to-front. ![]() This is the ZStack: views are shown on top of each other. In the above screenshot, you can see how a bit of text overlays a background image. Text(“A journey of a thousand miles\nstarts with a single step”) As we’ve discussed before, the ZStack will group views together back-to-front, along the depth axis (Z). See how the 2 subviews of the HStack are neatly organized horizontally and left-to-right? They’re centered in both axes by default. The Text views, however, are aligned leading, i.e. It’s important to note here that the default alignment for stacks is centered both horizontally and vertically. The first Text view in the VStack corresponds to the first line of text, shown on the right in the Preview. Text(“Zen and The Art of Motorcycle Maintenance”)Īs you can see in the screenshot above, the Live Preview in Xcode shows 3 Text views organized vertically – top-to-bottom – in a VStack. Here’s an example of a VStack with 3 Text views: Makes you wonder why they didn’t call it an XStack or DStack… VStack, HStack and ZStack in SwiftUI A button or Text view onto a background Image view, for example. Views in a ZStack can overlap, which means it’s ideal for creating UI stacks that overlay other views. The ZStack is in a category of its own, because it groups views together along the z- or depth axis, shown back-to-front. The HStack fits in the same category it’s the same as a VStack, except it groups subviews left-to-right along the horizontal axis. The VStack groups subviews together vertically, along the vertical axis, so top-to-bottom. You can, of course, combine VStacks, HStacks and ZStacks to create complex User Interfaces. Like other SwiftUI views, stacks can contain a maximum of 10 subviews. Stacks are static, so they’re different from List and table views, for example. You can compare stacks in SwiftUI with UIStackView in UIKit. ZStack, a depth-based stack, which shows views in a back-to-front list.HStack, a horizontal stack, which shows views in a left-to-right list.VStack, a vertical stack, which shows views in a top-to-bottom list.You can use 3 kinds of stacks with SwiftUI: Stack Layout with Alignment and SpacingĪ stack is a collection of SwiftUI views that are grouped together.Stream music, and reach out to a wider audience with the help of your own radio app.Ĭonnect with your congregation instantly by creating an app for your church.Ĭreate an online dating app and let your app users find the perfect match with just a swipe.Ĭreate a taxi booking app and let your users book a cab in real-time, track the ride, and reach their destination.
