# init(importedAs:conformingTo:)

Creates a type your app uses, but doesn’t own, based on an identifier and a supertype that it conforms to.

## Declaration

```swift
init(importedAs identifier: String, conformingTo parentType: UTType? = nil)
```

## Parameters

- `identifier`: The identifier of your type.
- `parentType`: A type to extend with this type.

## Discussion

Discussion Define a type with this initializer when you’re supporting a type that another app owns. For example, the following code uses another app’s type information to open or save files in its app: extension UTType {     /// The type of a supported file format.     public static var anotherFormat: UTType {         UTType(importedAs: "com.example.anotherformat")     } }
