Adjust List row separator insets

0
18

Starting from iOS 16 list row separators in SwiftUI are aligned by default to the leading text in the row, if text is present. It’s different from the iOS 15 behavior, where the insets of the separator do not adjust to the content of the row.

We also have some new SwiftUI APIs for customizing the insets of the separator.

Using listRowSeparatorLeading horizontal alignment guide, we can align the leading end of the row separator with any other horizontal guide of a view.

List(events)  event in
    HStack 
        DateLabel(date: event.date)
        EventNameLabel(name: event.name)
            .alignmentGuide(
                .listRowSeparatorLeading
            )  dimensions in
                dimensions[.leading]
            
    

If we need to adjust the trailing inset of the separator, we can use listRowSeparatorTrailing alignment guide.

List(events)  event in
    HStack 
        EventNameLabel(name: event.name)
        Spacer()
            .alignmentGuide(
                .listRowSeparatorTrailing
            )  dimensions in
                dimensions[.trailing]
            
        DateLabel(date: event.date)
