## Discussion

> Important:
> This property is available in iOS 12.5, and in iOS 13.5 and later.

This property contains eight risk-level values in the range 0-8, one for each range of attenuation.

- `attenuationLevelValues[0]` when attenuation > 73.
- `attenuationLevelValues[1`] when 73 >= attenuation > 63.
- `attenuationLevelValues[2]` when 63 >= attenuation > 51.
- `attenuationLevelValues[3]` when 51 >= attenuation > 33.
- `attenuationLevelValues[4]` when 33 >= attenuation > 27.
- `attenuationLevelValues[5]` when 27 >= attenuation > 15.
- `attenuationLevelValues[6]` when 15 >= attenuation > 10.
- `attenuationLevelValues[7]` when 10 >= attenuation.

> Note:
> On iOS 13.7 and 14.0, the framework ignores the values of this property. Instead, it uses `[1, 2, 3, 4, 5, 6, 7, 8]` for the attenuation level values.
