# unbounded

A picker discovery that only times out when the app tells it to.

```
static let unbounded: ASPickerDisplaySettings.DiscoveryTimeout
```

## Discussion

Use this timeout value if you set the picker display option [`filterDiscoveryResults`](/documentation/AccessorySetupKit/ASPickerDisplaySettings/Options-swift.struct/filterDiscoveryResults) and need unlimited time for filtering.
After performing manual discovery, perform the manual timeout by calling the [`ASAccessorySession`](/documentation/AccessorySetupKit/ASAccessorySession) method [`finishPickerDiscovery(completionHandler:)`](/documentation/AccessorySetupKit/ASAccessorySession/finishPickerDiscovery(completionHandler:)).
This process shows a timeout message if your filtering added no accessories to the picker, or returns silently if you updated the picker.
