# init(suiteName:className:dictionary:)

Initializes and returns a newly allocated instance of `NSScriptClassDescription`.

```
init?(suiteName: String, className: String, dictionary classDeclaration: [AnyHashable : Any]?)
```

## Parameters

`suiteName`

The name of the suite (in the application’s scriptability information) that the class belongs to. For example, `"AppName Suite"`.

`className`

The name of the class that this instance describes.

`classDeclaration`

A class declaration dictionary of the sort that is valid in script suite property list files. This dictionary provides information about the class such as its attributes and relationships.

## Return Value

The initialized instance. Returns `nil` if the event code value for the class description itself is missing or is not an `NSString`. Also returns `nil` if the superclass name or any of the subdictionaries of descriptions are not of the right type.

## Discussion

This method registers `self` with the application’s global instance of [`NSScriptSuiteRegistry`](/documentation/Foundation/NSScriptSuiteRegistry).
