Going Horizontal

Sometimes views belong side by side, not stacked down. For that you reach for the horizontal sibling of VStack. ➡️

Meet HStack

An HStack arranges its children horizontally, left to right. It is perfect for rows like an icon next to a label.

Your First HStack

Put views inside the HStack braces and they line up across the screen in the order you wrote them.

HStack {
    Text("Left")
    Text("Right")
}

Left to Right Order

In an HStack the first child sits on the leading edge and later children follow toward the trailing edge. Code order is left-to-right order.

Icon Plus Label

A classic HStack pairs an Image with a Text so an icon and its caption stay on one line, like a row in a settings screen.

HStack {
    Image(systemName: "bell")
    Text("Alerts")
}

Centered Vertically

By default an HStack aligns its children to the vertical center, so a tall image and short text line up neatly along their middles.

HStack Hugs Its Content

Just like VStack, an HStack shrinks to fit its children rather than filling the whole width. It takes only the space it needs.

Combining HStack and VStack

Nest an HStack inside a VStack to build a card: a title row on top and a detail row below. Mixing both directions builds real layouts.

VStack {
    Text("Title")
    HStack {
        Text("A")
        Text("B")
    }
}

HStack Is a View

An HStack is a view too, so modifiers like padding or background apply to the entire row at once, treating it as a single block.

Mixed Content Rows

An HStack happily holds different view types together, like a number, a label, and a button all sharing one horizontal line.

HStack {
    Text("42")
    Button("Add") { }
}

When to Reach for HStack

Use an HStack whenever items read left to right: a label and value, a toolbar of buttons, or an avatar beside a name.

Quick Check

Let's confirm how HStack lays things out.

Recap: Horizontal Rows

Great progress! An HStack lines views up left to right, centers them vertically, and pairs beautifully with VStack to build cards and rows. 🙌
