The iOS Simulator displays a contact list titled Everyone, showing one contact: Paul Hudson with the email paul@hackingwithswift.com. A blue checkmark indicates the contact is selected and a blue “Delete Selected” button appears at the bottom of the view. Below that, a tab bar highlights the Everyone tab and includes options like Contacted, Uncontacted, Me, and More.
