List members in a group channel

In Sendbird Chat SwiftUI, you can retrieve a list of members of a group channel through the GroupUserListView struct. This struct is used to display a list of channel members, operators, muted members, and banned users.

Note: If you set the starting point of your chat service to be the channel list, group channel, or channel settings, you can seamlessly guide your users to the member list view.

There are four different types of list view that display users or members of GroupChannel.

You can start building a member list view using the GroupMemberListView, GroupOperatorListView, GroupMutedMemberListView, or GroupBannedUserListView. Each struct can be used to create specific views tailored to different participant lists. Use the init(channelURL:) initializer to create the instance and display the view as shown below.

import SwiftUI
import SendbirdSwiftUI 

struct ContentView: View {
    var body: some View {
        GroupMemberListView(channelURL: {CHANNEL_URL})
    }
}

Sendbird Chat SwiftUI provides a View customization and DestinationViewBuilder.

• View customization: Our SwiftUI SDK allows you to selectively customize view elements. To learn more about the customization and our SwiftUI is designed, see the customization guide.
• DestinationViewBuilder: Use DestinationViewBuilder to customize the destination views that are navigatable from the group channel view.

Note : Visit our Github Sample to see the custom sample implementation for each item.

You can easily customize a specific part of a View, which particularly comes in handy when changing only a certain area in the View. To do so, use the View Builders that Sendbird has predefined and its a ViewConfig. The ViewConfig contains the data needed to render the view and its parameters can be found in the table below.

GroupMemberListView

GroupOperatorListView

GroupMutedMemberListView

GroupBannedUserListView

The following code demonstrates how to replace the view items using headerItem. All other {Component}Items can be used in the same way.

Note : When you customize a parent view, customizations in the child views will not be applied. For example, if you customize the titleView in the headerItem, the customizations of the coverImage or titleLabel in the lower view items will not be applied.

GroupUserListView(
    channelURL: {CHANNEL_URL},
    headerItem: {
        .init()
        .leftView { config in
            Text("Left")
                .foregroundStyle(.blue)
        }
    }
)

You can also customize the entire view area as desired. You simply need to return a SwiftUI View in the closure. The ViewConfig contains the data needed to render the view. Its parameters can be found in the table below.

The following code demonstrates how to replace the entire list area using the list parameter.

Note : When you customize a parent view, customizations in the child views will not be applied. For example, if you customize the entire area through the list, the customizations set in the listItem will not be applied.

GroupUserListView(
    channelURL: {CHANNEL_URL},
    list: { config in
        List(config.users, id: \.self) { user in
            HStack {
                Circle()
                    .frame(width: 12, height: 12)
                    .foregroundStyle(user.isOperator ? .green : .red)
                Text("\(user.refinedNickname())")
                    .foregroundStyle(.black)
            }
            .contentShape(Rectangle())
        }
    }
)

Sendbird Chat SwiftUI is designed to internally navigate from each view to its connected view. However, if you need to customize the destination view, you can do so by using the interface provided by the DestinationViewBuilder.

The following code demonstrates how to replace the channel settings view connected from the channel view.

GroupMemberListView(channelURL: {CHANNEL_URL})
    .inviteUserView { channelURL in
        InviteUserView(channelURL: channelURL)
    }

Note : If you've customized a child view of another view, you need to set the destination view for all the views from the top to the destination view.
