# hasBetterPath

If a connection has a better path, new connections would use a different interface.

```
var hasBetterPath: Bool { get }
```

## Discussion

Evaluates to <doc://com.apple.documentation/documentation/Swift/true> if a new connection attempt to the remote endpoint would use a different and preferred path. If the current connection is not viable, this can be used as a hint to try again. If the current connection is still viable, this can indicate that the system or user has a preference for the newly available network path. For example, if the connection is established over a cellular data network and Wi-Fi is now available, then the connection has a better path available and this property is set to <doc://com.apple.documentation/documentation/Swift/true>. Use the `initWithUpgradeForConnection:` initializer to create a new connection with the same parameters as the current connection. Use Key-Value Observing to watch this property.
