FirebaseStorage Framework Reference

Classes

The following classes are available globally.

  • StorageReference represents a reference to a Google Cloud Storage object. Developers can upload and download objects, as well as get/set object metadata, and delete an object at the path. See the Cloud docs for more details.

    Declaration

    Swift

    @available(iOS 13, tvOS 13, macOS 10.15, watchOS 7, *)
@objc(FIRStorageReference)
open class StorageReference : NSObject

  • Firebase Storage is a service that supports uploading and downloading binary objects, such as images, videos, and other files to Google Cloud Storage. Instances of Storage are not thread-safe, but can be accessed from any thread.

    If you call Storage.storage(), the instance will initialize with the default FirebaseApp, FirebaseApp.app(), and the storage location will come from the provided GoogleService-Info.plist.

    If you provide a custom instance of FirebaseApp, the storage location will be specified via the FirebaseOptions.storageBucket property.

    Declaration

    Swift

    @available(iOS 13, tvOS 13, macOS 10.15, watchOS 7, *)
@objc(FIRStorage)
open class Storage : NSObject

  • StorageDownloadTask implements resumable downloads from an object in Firebase Storage.

    Downloads can be returned on completion with a completion handler, and can be monitored by attaching observers, or controlled by calling pause(), resume(), or cancel().

    Downloads can currently be returned as Data in memory, or as a URL to a file on disk.

    Downloads are performed on a background queue, and callbacks are raised on the developer specified callbackQueue in Storage, or the main queue if left unspecified.

    Declaration

    Swift

    @available(iOS 13, tvOS 13, macOS 10.15, watchOS 7, *)
@objc(FIRStorageDownloadTask)
open class StorageDownloadTask : StorageObservableTask, StorageTaskManagement

  • Contains the prefixes and items returned by a StorageReference.list() call.

    Declaration

    Swift

    @available(iOS 13, tvOS 13, macOS 10.15, watchOS 7, *)
@objc(FIRStorageListResult)
open class StorageListResult : NSObject

  • Class which represents the metadata on an object in Firebase Storage.

    This metadata is returned on successful operations, and can be used to retrieve download URLs, content types, and a Storage reference to the object in question. Full documentation can be found in the GCS documentation

    Declaration

    Swift

    @available(iOS 13, tvOS 13, macOS 10.15, watchOS 7, *)
@objc(FIRStorageMetadata)
open class StorageMetadata : NSObject

  • An extended StorageTask providing observable semantics that can be used for responding to changes in task state.

    Observers produce a StorageHandle, which is used to keep track of and remove specific observers at a later date.

    Declaration

    Swift

    @available(iOS 13, tvOS 13, macOS 10.15, watchOS 7, *)
@objc(FIRStorageObservableTask)
open class StorageObservableTask : StorageTask

  • A superclass to all Storage tasks, including StorageUploadTask and StorageDownloadTask, to provide state transitions, event raising, and common storage for metadata and errors.

    Callbacks are always fired on the developer-specified callback queue. If no queue is specified, it defaults to the main queue. This class is thread-safe.

    Declaration

    Swift

    @available(iOS 13, tvOS 13, macOS 10.15, watchOS 7, *)
@objc(FIRStorageTask)
open class StorageTask : NSObject

  • StorageTaskSnapshot represents an immutable view of a task. A snapshot contains a task, storage reference, metadata (if it exists), progress, and an error (if one occurred).

    Declaration

    Swift

    @available(iOS 13, tvOS 13, macOS 10.15, watchOS 7, *)
@objc(FIRStorageTaskSnapshot)
open class StorageTaskSnapshot : NSObject

  • StorageUploadTask implements resumable uploads to a file in Firebase Storage.

    Uploads can be returned on completion with a completion callback, and can be monitored by attaching observers, or controlled by calling pause(), resume(), or cancel().

    Uploads can be initialized from Data in memory, or a URL to a file on disk.

    Uploads are performed on a background queue, and callbacks are raised on the developer specified callbackQueue in Storage, or the main queue if unspecified.

    Declaration

    Swift

    @available(iOS 13, tvOS 13, macOS 10.15, watchOS 7, *)
@objc(FIRStorageUploadTask)
open class StorageUploadTask: StorageObservableTask,
  StorageTaskManagement
