Documentation

Overview

Package uniformtypeidentifiers provides Go bindings for the UniformTypeIdentifiers framework.

Provide uniform type identifiers that describe file types for storage or transfer.

The [Uniform Type Identifiers](<doc://com.apple.uniformtypeidentifiers/documentation/UniformTypeIdentifiers>) framework provides a collection of common types that map to MIME and file types. Use these types in your project to describe the file types in your app. These descriptions help the system properly handle file storage formats or in-memory data for transfer — for example, transferring data to or from the pasteboard. The identifier types can also identify other resources, such as directories, volumes, or packages.

Essentials

  • Defining file and data types for your app: Declare uniform type identifiers to support your app’s proprietary data formats.
  • System-declared uniform type identifiers: Common types that the system declares.

Uniform type identifiers

  • UTType: A structure that represents a type of data to load, send, or receive.
  • UTTagClass: A type that represents tag classes.
  • UTTypeReference: An object that represents a type of data to load, send, or receive.

Key Types

  • UTType - An object that represents a type of data to load, send, or receive.

type UTType 

type UTType struct {
	objectivec.Object
}

An object that represents a type of data to load, send, or receive.

Overview

The UTType object 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, and helpful properties, preferredFilenameExtension and preferredMIMEType.

The UTType object 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.
