# extendedProperties

A property that indicates the characteristic defines additional properties in the extended properties descriptor.

## Declaration

```swift
static var extendedProperties: CBCharacteristicProperties { get }
```

## Discussion

Discussion This property is only available for a remote peripheral’s service’s characteristic. You can’t use this property with a local characteristic, that is, a CBMutableCharacteristic that you publish using the add(_:) method of the CBPeripheralManager class.
