# predicateForObjects(withDeviceProperty:allowedValues:)

Returns a predicate that matches all objects created by devices with the specified properties.

## Declaration

```swift
class func predicateForObjects(withDeviceProperty key: String, allowedValues: Set<String>) -> NSPredicate
```

## Parameters

- `key`: A string specifying the device’s property. For a list of valid keys, see Valid Device Property Keys.
- `allowedValues`: A set of strings. These strings represent the target property values.

## Return Value

Return Value A predicate that matches all objects created by a device whose specified property matches one of the allowed values.

## Discussion

Discussion Use this convenience method to create a predicate that finds all the objects saved by matching devices. These predicates let you match multiple values for a single property. For example, you can create a single predicate that matches a number of different manufacturer values. The following sample shows how to create a predicate that matches a list of device model names.
