auto repeat pageview in swiftui - swiftui

Question

I have a swiftui project. I am using pageview. Normally, when it comes to the last page, it does not scroll further because the pages are finished. What I want is this: the pages continue after reaching the last page. Let's start again from the first page. so I want my page order to be like this:
page 1 -> page 2 -> page 3 -> page 1 -> page 2 -> page 3 -> page 1 .....
I want it to repeat itself like this all the time.
struct PageControllerView: View {
var body: some View {
TabView {
Text("page 1")
Text("page 2")
Text("page 3")
}
.tabViewStyle(PageTabViewStyle(indexDisplayMode: .never))
}
}

Well you need to use the TabView with a selection:
struct PageControllerView: View {
#State var selection = 1
var body: some View {
TabView(selection: $selection) {
Text("page 3").tag(0) //same as last view for swipe effect
Text("page 1").tag(1)
Text("page 2").tag(2)
Text("page 3").tag(3)
Text("page 1").tag(4) //same as first view for swipe effect
}//.tabViewStyle(PageTabViewStyle()) BTW, You don't need that
.tabViewStyle(PageTabViewStyle(indexDisplayMode: .never))
.onChange(of: selection) { newValue in
if selection == 4 { //last tag + 1
selection = 1 //first tag
}else if selection == 0 { //first tag - 1
selection = 3 //last tag
}
}
}
}
This also works with ForEach, but don't forget to choose a suitable tag.
