Example #1

Create a vertical stack of views, separated by dividers.

View code

structDividedVStack<Content:View>:View{@ViewBuilderletcontent:Contentvarbody:someView{Extract(content){ views inVStack{letfirst= views.first?.id
ForEach(views){ view inif view.id != first {Divider()}
view
}}}}}

Usage

DividedVStack{Text("View 1")Text("View 2")Text("View 3")}

Result

Example #2

Create a vertical stack of views, only keeping views at indexes with a multiple of 2.

View code

structIntervalVStack<Content:View>:View{@ViewBuilderletcontent:Contentvarbody:someView{Extract(content){ views inVStack{ForEach(Array(zip(views.indices, views)), id: \.1.id){ index, view inif index.isMultiple(of:2){
view
}}}}}}

Usage

IntervalVStack{ForEach(0..<10){ index inText("Index: \(index)")}}

Result

Example #3

Create a stack of views, returning multiple views as a result, allowing it to be wrapped by another view. When modifiers are applied, they apply to each view returned. Note the use of ExtractMulti rather than just Extract.

View code

structDivided<Content:View>:View{@ViewBuilderletcontent:Contentvarbody:someView{ExtractMulti(content){ views inletfirst= views.first?.id
ForEach(views){ view inif view.id != first {Divider()}
view
}}}}

Usage

HStack{Divided{Text("View 1")Text("View 2")Text("View 3")}.border(Color.red)}
