The Group view does not have any visual effect on its own it is simply a way to group views together and apply layout and styling to them.Īs long as the total number of items does not exceed 10, the Group view can be used to group any number of views. This is particularly important because, for underlying technical reasons, you can only add up to 10 views to a parent view at a time. In SwiftUI, the Group view is a container that wraps a group of views and allows you to apply layout and styling to them as a unit. If you need several views to act as one for example, to transition together then you should use SwiftUI’s Group view. In order to introduce more than 10 views within a VStack, an HStack, we can use different strategies. Using stacks in SwiftUI allows you to arrange multiple views into a single organized view with certain properties.
If we add, for example, 11 Text elements in a VStack, due to this limitation in ViewBuild, the eleventh Text element is marked with the error ‘Extra argument in call’. SwiftUI gives us two environment values to monitor the current size class of our app, which in practice means we can show one layout when space is restricted and another when space is plentiful. Display groups of views in a scrollable container Implementing repeating views or groups of views can be as simple as wrapping them in an HStack or VStack inside a ScrollView. The limitation you noticed is caused by the fact that the function with the most views only accepts 10 views. You can add scrolling by wrapping stacks inside a ScrollView, and switch to lazy stacks as performance issues arise. You can see that there are numerous instances of the buildBlock method, each taking a different number of views as parameters, if you look at the ViewBuilder documentation. VStack, HStack, ZStack… are views that are built using ViewBuilder. Take your career further with a Kodeco Personal Plan. HStack, VStack & ZStack Get immediate access to this and 4,000+ other videos and books. This is so because VStack, HStack, and ZStack are constructed as generic structures, and the type parameter controls the amount of views that can be directly included in them.

In SwiftUI there is NavigationView option to create the Navigation bar.
