# propertyListFromData(_:mutabilityOption:format:errorDescription:)

This method is deprecated. Use [`data(fromPropertyList:format:options:)`](/documentation/Foundation/PropertyListSerialization/data(fromPropertyList:format:options:)) instead.

```
class func propertyListFromData(_ data: Data, mutabilityOption opt: PropertyListSerialization.MutabilityOptions = [], format: UnsafeMutablePointer<PropertyListSerialization.PropertyListFormat>?, errorDescription errorString: UnsafeMutablePointer<NSString?>?) -> Any?
```

## Parameters

`data`

A data object containing a serialized property list.

`opt`

The options used to create the property list. For possible values, see [`PropertyListSerialization.MutabilityOptions`](/documentation/Foundation/PropertyListSerialization/MutabilityOptions).

`format`

If the property list is valid, upon return contains the format. `format` can be `nil`, in which case the property list format is not returned. For possible values, see [`PropertyListSerialization.PropertyListFormat`](/documentation/Foundation/PropertyListSerialization/PropertyListFormat).

`errorString`

Upon return, if the conversion is successful, `errorString` is `nil`. If the conversion fails, upon return contains a string describing the nature of the error.

## Return Value

A property list object corresponding to the representation in `data`. If data is not in a supported format, returns `nil`.

## See Also

[`class func propertyList(from: Data, options: PropertyListSerialization.ReadOptions, format: UnsafeMutablePointer<PropertyListSerialization.PropertyListFormat>?) throws -> Any`](/documentation/Foundation/PropertyListSerialization/propertyList(from:options:format:))

Creates and returns a property list from the specified data.
