KeyPaths¶

Keypath Basics

```swift struct Feature { let showView: Bool let showNotification: Bool let name: String
} let features: [Feature] = [ Feature(showView: true , showNotification: false , name: "Kay"), Feature(showView: true , showNotification: true , name: "Nay"), Feature(showView: true , showNotification: false , name: "Say") ]

let showFeatureNotifications = features .map(.showNotification)

print(showFeatureNotifications) // [false, true, false]
