# UTType

A structure that represents a type of data to load, send, or receive.

```
struct UTType
```

## Overview

The [`UTType`](/documentation/UniformTypeIdentifiers/UTType-swift.struct) instance may represent files on disk, abstract data types with no on-disk representation, or entirely unrelated hierarchical classification systems, such as hardware. Each instance has a unique [`identifier`](/documentation/UniformTypeIdentifiers/UTType-swift.struct/identifier), and helpful properties, such as [`preferredFilenameExtension`](/documentation/UniformTypeIdentifiers/UTType-swift.struct/preferredFilenameExtension) and [`preferredMIMEType`](/documentation/UniformTypeIdentifiers/UTType-swift.struct/preferredMIMEType).

> Note:
> The system includes static declarations for many common types, which you can look up by identifier, filename extension, or MIME type.

A [`UTType`](/documentation/UniformTypeIdentifiers/UTType-swift.struct) instance may provide additional information related to the type. For example, it may include a localized user-facing description, a reference URL to technical documentation about the type, or its version number. You can look up types by their conformance to get either a type or a list of types that are relevant to your use case.

To define your own types in your app’s `Info.plist`, see [Defining file and data types for your app](/documentation/UniformTypeIdentifiers/defining-file-and-data-types-for-your-app).

## Topics

### Looking up a type

[`types(tag:tagClass:conformingTo:)`](/documentation/UniformTypeIdentifiers/UTType-swift.struct/types(tag:tagClass:conformingTo:))

Returns an array of types from the provided tag and tag class.

### Creating a type

[`init(_:)`](/documentation/UniformTypeIdentifiers/UTType-swift.struct/init(_:))

Creates a type based on an identifier.

[`init(mimeType:conformingTo:)`](/documentation/UniformTypeIdentifiers/UTType-swift.struct/init(mimeType:conformingTo:))

Creates a type based on a MIME type and a supertype that it conforms to.

[`init(filenameExtension:conformingTo:)`](/documentation/UniformTypeIdentifiers/UTType-swift.struct/init(filenameExtension:conformingTo:))

Creates a type based on a filename extension and an existing supertype that it conforms to.

[`init(tag:tagClass:conformingTo:)`](/documentation/UniformTypeIdentifiers/UTType-swift.struct/init(tag:tagClass:conformingTo:))

Creates a type based on a tag, a tag class, and a supertype that it conforms to.

[`init(exportedAs:conformingTo:)`](/documentation/UniformTypeIdentifiers/UTType-swift.struct/init(exportedAs:conformingTo:))

Creates a type your app owns based on an identifier and a supertype that it conforms to.

[`init(importedAs:conformingTo:)`](/documentation/UniformTypeIdentifiers/UTType-swift.struct/init(importedAs:conformingTo:))

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

### Identifying a type

### Checking a type’s relationship to another type

[`supertypes`](/documentation/UniformTypeIdentifiers/UTType-swift.struct/supertypes)

The set of types the type directly or indirectly conforms to.

[`conforms(to:)`](/documentation/UniformTypeIdentifiers/UTType-swift.struct/conforms(to:))

Returns a Boolean value that indicates whether a type conforms to the type.

[`isSubtype(of:)`](/documentation/UniformTypeIdentifiers/UTType-swift.struct/isSubtype(of:))

Returns a Boolean value that indicates whether a type is higher in a hierarchy than the type.

[`isSupertype(of:)`](/documentation/UniformTypeIdentifiers/UTType-swift.struct/isSupertype(of:))

Returns a Boolean value that indicates whether a type is lower in a hierarchy than the type.
