+The `name` property exposes the assigned device name by the owner. This value is obtained from the property `UIDevice.current.name`.
+This property requires special entitlement [com.apple.developer.device-information.user-assigned-device-name](https://developer.apple.com/documentation/bundleresources/entitlements/com_apple_developer_device-information_user-assigned-device-name) in iOS 16 and later, otherwise, the property `name` will always be `iPad` or `iPhone`.
