There are several ways to group views together in SwiftUI. If you want to treat multiple views as a single entity and apply a common set of modifications or layouts, you can use the Group
view in SwiftUI. It is important to note that, due to technical limitations, a parent view can only contain a maximum of 10 child views at once. Using a Group
view can help you work around this limitation.
- You can use a
Group
view to wrap a collection of views together. TheGroup
view doesn’t generate any visual output of its own, but it allows you to apply modifiers or layout to a group of views as a single entity. Note: If you attempt to add more than 10 views to a parent view in SwiftUI, you may encounter an error similar toambiguous reference to member 'buildBlock()'
. This is because the view building system in SwiftUI is only designed to support up to 10 views at a time. Attempting to add more than 10 views may cause errors and is not supported.
For example:
// Error ambiguous reference to member 'buildBlock()’ VStack { Text("Text 1") Text("Text 2") Text("Text 3") Text("Text 4") Text("Text 5") Text("Text 6") Text("Text 7") Text("Text 8") Text("Text 9") Text("Text 10") Text("Text 11") Text("Text 12") } // No error after grouping VStack { Group { Text("Text 1") Text("Text 2") Text("Text 3") Text("Text 4") Text("Text 5") Text("Text 6") Text("Text 7") } Group { Text("Text 8") Text("Text 9") Text("Text 10") Text("Text 11") Text("Text 12") } }
- You can use a
VStack
(vertical stack) orHStack
(horizontal stack) to layout a collection of views in a horizontal or vertical line.
- You can use a
ZStack
(z-axis stack) to lay out views on top of each other.
- You can use a
List
to display a collection of views in a vertically scrolling list.
VStack { Text("Text 1") Text("Text 2") } HStack { Text("Text 1") Text("Text 2") } ZStack { Text("Text 1") Text("Text 2") } List { Text("Text 1") Text("Text 2") }
