When designing a TabView you have the option to add an icon for each tab using a system image, using the `systemImage` parameter to `Label`:

```swift
TabView {
    Text("First")
        .tabItem {
            Label("First", systemImage: "tray")
        }
}
```

In this case we use `tray`.

How do you find out which other icons you can use? 

Apple created an app for this, called **SF Symbols**. Download it from <https://developer.apple.com/design/downloads/SF-Symbols.dmg>, install it on your Mac and once you open it, you can browse over 1500 symbols and see their name:
