How to change List Row separator color in SwiftUI

In iOS 15, SwiftUI got a new modifier, listRowSeparatorTint(_:edges:), to customize List Row separator color.

How to change the SwiftUI List Row separator color

To change a list row separator color, we apply listRowSeparatorTint(_:edges:) to a list row, passing the separator color as an argument.

In this example, we change the separators' color to pink.

struct ContentView: View {
    var body: some View {
        NavigationView {
            List(0..<10) { i in
                Text("Row \(i.description)")
                    .listRowSeparatorTint(.pink)
            }
            .navigationTitle("List")
        }
    }
}

Make sure you apply listRowSeparatorTint(_:edges:) to a list row, not a List view.

A list row separator color doesn't need to be the same.

You can have a different row separator color for each row by applying different colors for each row.

Here is an example of list rows with different separator colors.

struct ContentView: View {
    var body: some View {
        NavigationView {
            List {
                Text("Row 0")
                    .listRowSeparatorTint(.pink)
                Text("Row 1")
                    .listRowSeparatorTint(.indigo)
                Text("Row 2")
                    .listRowSeparatorTint(.yellow)
                Text("Row 3")
                    .listRowSeparatorTint(.green)
                Text("Row 4")
                    .listRowSeparatorTint(.orange)
                Text("Row 5")
                    .listRowSeparatorTint(.blue)
                Text("Row 6")
                    .listRowSeparatorTint(.brown)
            }
            .navigationTitle("List")
        }
    }
}

How to change the Top or Bottom List Row separator color

List row separators can be presented above and below a row.

Some list styles like .insetGrouped and .sidebar might decide not to display separators for some edges.

But some list styles, e.g., .plain, show both separators on both top and bottom edge.

The .listRowSeparatorTint(_:edges:) modifier has an optional second argument that you can specify which separator edges the color applies. By default, it's applied to all edges.

The following example show s plain list style whose top row separators are tinted.

struct ContentView: View {
    var body: some View {
        NavigationView {
            List(0..<10) { i in
                Text("Row \(i.description)")
                    .listRowSeparatorTint(.pink, edges: .top)
            }
            .listStyle(.plain)
            .navigationTitle("List")
        }
    }
}

As you can see, only the top separators are colored. This leaves the bottom separator with the default gray color.
