In group channel list, how to selectively customize colors of view properties in only a specific cell?

Question

How do I customize the color of view properties of only specific preview cells of a group channel list, and not affect the global theme?

Guide & Snippet

1. Create custom SBUGroupChannelCell
First create your custom GroupChannelCell that will be used as a table view cell of a table view of SBUGroupChannelListViewController.
Modify properties according to your needs by overriding the methods of SBUGroupChannelCell.
In this example, we override setupStyles() since we want to change the color of a lable.

class CustomGroupChannelCell: SBUGroupChannelCell {
    override func setupStyles() {
        super.setupStyles()
        if channel?.name == "Target Channel" {   // <- selective customization
            self.messageLabel.textColor = .purple
        }
    }
}

2. Register your custom cell
The cell type must be registered in SBUGroupChannelListModule's ListComponent. You can register your custom cell type by overriding setupViews() method in SBUGroupChannelListModule.List.

class CustomGroupChannelListModuleListComponent: SBUGroupChannelListModule.List {
    override func setupViews() {
        super.setupViews()
        self.register(channelCell: CustomGroupChannelCell())
    }
}

3. Set your custom group channel list module's list component type
In order for SendbirdUIKit to be able to use your custom GroupChannelListModuleListComponent, you must hook it in SBUModuleSet using the code below.

// Run this code anywhere before presenting the `SBUGroupChannelListViewController`.
SBUModuleSet.GroupChannelListModule.ListComponent = CustomGroupChannelListModuleListComponent.self
