A slightly more flexible SwiftUI PageView.
This uses TabView with a .page tabViewStyle to implement the basic paging behaviour, but it accepts a second closure should be a view builder defining the index view to use instead of the default dots.
It also allows you to specify the alignment and padding of the index view - so you can inset it more than usual or move it to the top or to one side.
PageView(selection: $selection, indexAlignment: .bottomLeading, indexPadding: 40.0) {
ForEach(items) { item in
Text(item)
.tag(item)
}
} index: {
DotsIndexView(currentIndex: selection)
}
By default, PageView uses a ZStack to place its index view on top of its content.
Unfortunately this seems to cause some issues that prevent the index view from detecting taps/clicks.
As a workaround, there is also a VStackPageView variant, which stacks the index view below the content.
This variant has no problems detecting taps, and is a better choice if you want the index view at the bottom of the content.
