The full source code for this can be found here. This is what it looks like after we add the frame view modifier to the Text view: ConclusionĪnd that is it! SwiftUI makes it incredibly easy to have a child view fill the parent view, but, when doing this, keep in mind the order of the view modifiers. To make the Text view fill up the parent view, we can add the following line inbetween the forgroundColor and background view modifiers.
We can also see that the Text view is centered and small. This is what the above code looks like when I run it:Īs we can see, we have a VStack where the frame has a width of 200 and a height of 200. border(Color.red, width: 1) // Set VStack border to make it visible
frame(width: 200, height: 200) // Set VStack frame width and height I am going to start off with a very basic layout, the code will look like this: struct ContentView: View. infinity when using the frame view modifier. TLDR: To make a view fill the screen or parent view, you can set the maxHeight and maxWidth to. Luckily for us SwiftUI makes this very easy to do. It is often required that a view fill a space, whether it is width, height or both.
Lazy vstack how to#
Between the ContentView struct declaration and its body, create an array of SF symbol names called imageNames.In this tutorial I will show you how to make a view fill the width or height of the parent view or fill the screen.This is the result: As you can see, VStack arranges the Text (), HStack, and Zstack as a top-to-bottom list. Each of them have views inside, like Text () and Image (). In the example below, you will see a combination of VStack, HStack, and ZStack. Each scroll view will contain SF symbols for the letters A–L: A good way to achieve this is using a combination of Stacks. We will add two scroll views to a VStack component: one horizontal and one vertical. They follow Apple's San Francisco system font and automatically ensure optical vertical alignment for different sizes and weights.
SF Symbols is a set of over 2,400 symbols provided by Apple.

Optional: Download the San Francisco ( SF) Symbols app here. Let's start by creating a SwiftUI project called ScrollViewApp. vertical() modifiers as the first parameter to the scroll view. Scroll views are vertical by default and can be made to scroll horizontally or vertically by passing in the. They automatically size themselves to the area where they are placed. SwiftUI scroll views are used to easily create scrolling containers.
Other recipes will help you to make some of the new SwiftUI 2.0 components backward-compatible with iOS 13, such as the Map View or the Sign in with Apple View. The recipes cover the foundations of SwiftUI as well as the new SwiftUI 2.0 features introduced in iOS 14. In this recipe-based book, you’ll work with SwiftUI and explore a range of essential techniques and concepts that will help you through the development process. SwiftUI is an innovative and simple way to build beautiful user interfaces (UIs) for all Apple platforms, right from iOS and macOS through to watchOS and tvOS, using the Swift programming language.
