# dictionaryWithValues(forKeys:)

Returns a dictionary containing the property values identified by each of the keys in a given array.

```
func dictionaryWithValues(forKeys keys: [String]) -> [String : Any]
```

## Parameters

`keys`

An array containing `NSString` objects that identify properties of the receiver.

## Return Value

A dictionary containing as keys the property names in `keys`, with corresponding values being the corresponding property values.

## Discussion

The default implementation invokes [`value(forKey:)`](/documentation/ObjectiveC/NSObject-swift.class/value(forKey:)) for each key in `keys` and substitutes `NSNull` values in the dictionary for returned `nil` values.

## See Also

[`-  setValuesForKeysWithDictionary:`](/documentation/ObjectiveC/NSObject-swift.class/setValuesForKeys(_:))

Sets properties of the receiver with values from a given dictionary, using its keys to identify the properties.
