A SwiftUI library that allows you to add native or custom section styles within the ScrollView SwiftUI component

ScrollViewSectionKit

A SwiftUI library that allows you to add native (plain, grouped, insetGrouped) or custom section styles within the ScrollView SwiftUI component.

Overview

  • ? Made with 100% SwiftUI.
  • ? Lightweight, no external dependencies.
  • ✅ The API tries to mimic Apple’s List component but you can use it within the ScrollView component.
  • ? The predefined .plain, .grouped and .insetGrouped section styles, but you can also define a completely custom section style.
  • ? Tested in multiple production applications.
  • ? Well documented API.

Requirements

  • iOS 14.0+
  • watchOS 7.0+
  • tvOS 14.0+
  • macOS 11.0+

Usage

import ScrollViewSectionKit

struct ContentView: View {
    
    var body: some View {
        ScrollView {
            VStack(spacing: 0.0) {
                ScrollViewSection {
                    Text("This is a 1st row.")
                    Text("This is a 2nd row.")
                } header: {
                    Text("Section header".uppercased())
                } footer: {
                    Text("Section footer")
                }
            }
        }
        .scrollViewSectionStyle(.insetGrouped)
        .scrollViewSectionBackgroundColor(.clear)
        .background {
            Color(uiColor: UIColor.systemGroupedBackground)
                .ignoresSafeArea()
        }
    }
    
}

See example application for all examples and advanced usage.

Configuration

Section – Style

You can customize the appearance of section by applying different styles using the scrollViewSectionStyle(_ style: any ScrollViewSectionStyle) modifier. This modifier can be used globally or per section. The library already contains the .plain, .grouped and .insetGrouped styles.

In the following example the first ScrollViewSection uses the .grouped style because it is set as part of the ScrollView component but the second ScrollViewSection uses .insetGrouped style. This is because under the hood the scrollViewSectionStyle(_ style: any ScrollViewSectionStyle) modifier is using EnvironmentKey. This means that you can use this modifier to set a global style for the entire application.

import ScrollViewSectionKit

struct ContentView: View {
    
    var body: some View {
        ScrollView {
            VStack(spacing: 0.0) {
                ScrollViewSection {
                    Text("This is a 1st row.")
                    Text("This is a 2nd row.")
                } header: {
                    Text("Section header".uppercased())
                } footer: {
                    Text("Section footer")
                }
                ScrollViewSection {
                    Text("This is a 1st row.")
                    Text("This is a 2nd row.")
                } header: {
                    Text("Section header".uppercased())
                } footer: {
                    Text("Section footer")
                }
                .scrollViewSectionStyle(.insetGrouped)
            }
        }
        .scrollViewSectionStyle(.grouped)
        .scrollViewSectionBackgroundColor(.clear)
        .background {
            Color(uiColor: UIColor.systemGroupedBackground)
                .ignoresSafeArea()
        }
    }
}

Section – Background Color

You can customize the appearance of section by applying different background colors using the scrollViewSectionBackgroundColor(_ color: Color) modifier. This modifier can be used globally or per section.

In the following example the first ScrollViewSection uses the .blue.opacity(0.28) background color because it is set as part of the ScrollView component but the second ScrollViewSection uses .orange.opacity(0.28) background color. This is because under the hood the scrollViewSectionBackgroundColor(_ color: Color) modifier is using EnvironmentKey. This means that you can use this modifier to set a global style for the entire application.

import ScrollViewSectionKit

struct ContentView: View {
    
    var body: some View {
        ScrollView {
            VStack(spacing: 0.0) {
                ScrollViewSection {
                    Text("This is a 1st row.")
                    Text("This is a 2nd row.")
                } header: {
                    Text("Section header".uppercased())
                } footer: {
                    Text("Section footer")
                }
                ScrollViewSection {
                    Text("This is a 1st row.")
                    Text("This is a 2nd row.")
                } header: {
                    Text("Section header".uppercased())
                } footer: {
                    Text("Section footer")
                }
                .scrollViewSectionStyle(.insetGrouped)
                .scrollViewSectionBackgroundColor(.orange.opacity(0.28))
            }
        }
        .scrollViewSectionStyle(.grouped)
        .scrollViewSectionBackgroundColor(.blue.opacity(0.28))
        .background {
            Color(uiColor: UIColor.systemGroupedBackground)
                .ignoresSafeArea()
        }
    }
}

Row – Background Color

You can customize the appearance of row by applying different background colors using the scrollViewRowBackgroundColor(_ color: Color) modifier. This modifier can be used per section or per row.

In the following example the second row of the first section uses the .blue.opacity(0.28) background color because it is set as part of row. The first row of the second section, on the other hand, uses .green.opacity(0.28) background color because the entire section uses this modifier and the last row of the second section uses the .orange.opacity(0.28) background color.

import ScrollViewSectionKit

struct ContentView: View {
    
    var body: some View {
        ScrollView {
            VStack(spacing: 0.0) {
                ScrollViewSection {
                    Text("This is a 1st row.")
                    Text("This is a 2nd row.")
                        .scrollViewRowBackgroundColor(.blue.opacity(0.28))
                } header: {
                    Text("Section header".uppercased())
                } footer: {
                    Text("Section footer")
                }
                ScrollViewSection {
                    Text("This is a 1st row.")
                    Text("This is a 2nd row.")
                        .scrollViewRowBackgroundColor(.orange.opacity(0.28))
                } header: {
                    Text("Section header".uppercased())
                } footer: {
                    Text("Section footer")
                }
                .scrollViewSectionStyle(.insetGrouped)
                .scrollViewRowBackgroundColor(.green.opacity(0.28))
            }
        }
        .scrollViewSectionStyle(.grouped)
        .scrollViewSectionBackgroundColor(.clear)
        .background {
            Color(uiColor: UIColor.systemGroupedBackground)
                .ignoresSafeArea()
        }
    }
}

Row – Insets

You can also customize the appearance of row by applying different row insets using the scrollViewRowInsets(_ insets: EdgeInsets?) modifier. This modifier can be used per section or per row.

In the following example the whole first section uses EdgeInsets(top: 0.0, leading: 40.0, bottom: 0.0, trailing: 0.0) row insets because the entire section uses this modifier. The first row of the second section, on the other hand, uses EdgeInsets(top: 0.0, leading: 40.0, bottom: 0.0, trailing: 0.0) row insets because just this one row uses this modifier and the last row uses default row insets.

import ScrollViewSectionKit

struct ContentView: View {
    
    var body: some View {
        ScrollView {
            VStack(spacing: 0.0) {
                ScrollViewSection {
                    Text("This is a 1st row.")
                    Text("This is a 2nd row.")
                } header: {
                    Text("Section header".uppercased())
                } footer: {
                    Text("Section footer")
                }
                .scrollViewRowInsets(EdgeInsets(top: 0.0, leading: 40.0, bottom: 0.0, trailing: 0.0))
                ScrollViewSection {
                    HStack(spacing: 10.0) {
                        Image(systemName: "person.fill")
                            .resizable()
                            .scaledToFit()
                            .frame(width: 20.0, height: 20.0)
                        Text("This is a 1st row.")
                    }
                    .scrollViewRowInsets(EdgeInsets(top: 0.0, leading: 40.0, bottom: 0.0, trailing: 0.0))
                    Text("This is a 2nd row.")
                } header: {
                    Text("Section header".uppercased())
                } footer: {
                    Text("Section footer")
                }
                .scrollViewSectionStyle(.insetGrouped)
            }
        }
        .scrollViewSectionStyle(.grouped)
        .scrollViewSectionBackgroundColor(.clear)
        .background {
            Color(uiColor: UIColor.systemGroupedBackground)
                .ignoresSafeArea()
        }
    }
}

Row – Separator Insets

In the previous example we adjusted the row insets but the separators still use the default insets. We can change this by using scrollViewRowSeparatorInsets(_ insets: EdgeInsets?) modifier. This modifier can be used per section or per row.

In the following example the whole first section uses EdgeInsets(top: 0.0, leading: 40.0, bottom: 0.0, trailing: 0.0) row separator insets because the entire section uses this modifier. The first row of the second section, on the other hand, uses EdgeInsets(top: 0.0, leading: 70.0, bottom: 0.0, trailing: 0.0) row separator insets because just this one row uses this modifier and the last row uses default row insets.

import ScrollViewSectionKit

struct ContentView: View {
    
    var body: some View {
        ScrollView {
            VStack(spacing: 0.0) {
                ScrollViewSection {
                    Text("This is a 1st row.")
                    Text("This is a 2nd row.")
                } header: {
                    Text("Section header".uppercased())
                } footer: {
                    Text("Section footer")
                }
                .scrollViewRowInsets(EdgeInsets(top: 0.0, leading: 40.0, bottom: 0.0, trailing: 0.0))
                .scrollViewRowSeparatorInsets(EdgeInsets(top: 0.0, leading: 40.0, bottom: 0.0, trailing: 0.0))
                ScrollViewSection {
                    HStack(spacing: 10.0) {
                        Image(systemName: "person.fill")
                            .resizable()
                            .scaledToFit()
                            .frame(width: 20.0, height: 20.0)
                        Text("This is a 1st row.")
                    }
                    .scrollViewRowInsets(EdgeInsets(top: 0.0, leading: 40.0, bottom: 0.0, trailing: 0.0))
                    .scrollViewRowSeparatorInsets(EdgeInsets(top: 0.0, leading: 70.0, bottom: 0.0, trailing: 0.0))
                    Text("This is a 2nd row.")
                } header: {
                    Text("Section header".uppercased())
                } footer: {
                    Text("Section footer")
                }
                .scrollViewSectionStyle(.insetGrouped)
            }
        }
        .scrollViewSectionStyle(.grouped)
        .scrollViewSectionBackgroundColor(.clear)
        .background {
            Color(uiColor: UIColor.systemGroupedBackground)
                .ignoresSafeArea()
        }
    }
}

Row – Context Menu

You can also add a context menu for the row by applying the scrollViewRowContextMenu(@ViewBuilder _ menuItems: @escaping () -> some View) modifier. This modifier can be used per section or per row.

In the following example the second row of the first section uses multiple buttons with the Divider component between them.

import ScrollViewSectionKit

struct ContentView: View {
    
    var body: some View {
        ScrollView {
            VStack(spacing: 0.0) {
                ScrollViewSection {
                    Text("This is a 1st row.")
                    Text("This is a 2nd row.")
                        .scrollViewRowContextMenu {
                            Button {
                                
                            } label: {
                                Label("Star", systemImage: "star")
                            }
                            Button {
                                
                            } label: {
                                Label("Profile", systemImage: "person")
                            }
                            Divider()
                            Button(role: .destructive) {
                                
                            } label: {
                                Label("Block", systemImage: "hand.raised")
                            }
                        }
                } header: {
                    Text("Section header".uppercased())
                } footer: {
                    Text("Section footer")
                }
                ScrollViewSection {
                    Text("This is a 1st row.")
                    Text("This is a 2nd row.")
                } header: {
                    Text("Section header".uppercased())
                } footer: {
                    Text("Section footer")
                }
                .scrollViewSectionStyle(.insetGrouped)
            }
        }
        .scrollViewSectionStyle(.grouped)
        .scrollViewSectionBackgroundColor(.clear)
        .background {
            Color(uiColor: UIColor.systemGroupedBackground)
                .ignoresSafeArea()
        }
    }
    
}
