Navigating a Page Control about swiftuix

@writing-shed check out PreviousButton and NextButton. PaginationView exposes something called a ProgressionController which can be used to move to next/previous.

Thanks for this. I have tried it but found that the environment variable is set to nil. Here's my code:

struct TextEditView: View {
    @Environment(\.progressionController) var progressionController
    var text:String
    var ranges:PageRanges
    var body: some View {
        VStack {
            HStack {
                PreviousButton(action: {
                    self.progressionController?.moveToPrevious()
                }) {
                    Text("previous")
                }
                NextButton(action: {
                    self.progressionController?.moveToNext()
                })
                {
                    Text("next")
                }
            }
            PaginationView(axis: .horizontal, transitionStyle: .scroll, showsIndicators: false) {
                ForEach(ranges, id:\.id) { pageRange in
                    VStack {
                        TextView(text: self.text, range: pageRange)
                        Text("page \(pageRange.page)")
                    }
                    
                }
            }
        }
    }
}

@writing-shed apologies for not seeing the comment! PreviousButton and NextButton are meant to be used within PaginationView content.

If you want to control pagination from outside, you have to maintain a @State variable for your current page index and pass it to PaginationView's currentPageIndex(_:) modifier.

Reopening until its completely resolved :)
