# properties

The properties of the characteristic.

## Declaration

```swift
var properties: CBCharacteristicProperties { get set }
```

## Discussion

Discussion The properties of a characteristic determine the access to and use of the characteristic’s value and descriptors. For a list of the possible values representing the properties of a characteristic, see the CBCharacteristicProperties enumeration in CBCharacteristic. However, you can’t use the broadcast and extendedProperties characteristic properties when creating a mutable characteristic.
