  • Breaking change: Updated minimum macOS version to 10.12.
  • Breaking change: The pods developed in this repo are no longer hard coded to be built as static frameworks. Instead, their linkage will be controlled by the Podfile. Use the Podfile option use_frameworks! :linkage => :static to get the Firebase 6.x linkage behavior. See this linking guide for mode details (#2022).
  • Breaking change: The version must now be specified for the two Swift-only Firebase CocoaPods in the Podfile like pod 'FirebaseFirestoreSwift', '~> 7.0-beta'.
  • Firebase now requires a minimum CocoaPods version of 1.9.0.
  • Added Swift Package Manager support for Firebase Messaging (#5641).
  • Added Swift Package Manager support for Auth, Crashlytics, Messaging, and Storage watchOS targets (#6584).

Swift Extensions

  • Added conditional conformance to the Hashable protocol for the @DocumentID, @ExplicitNull, and @ServerTimestamp property wrappers.

  • Removed support for wrapping NSDate in a @ServerTimestamp property wrapper. This never actually worked because NSDate is not Codable.

Cloud Firestore

  • Firestore previously required that every document read in a transaction must also be written. This requirement has been removed, and you can now read a document in a transaction without writing to it.
  • Improved the performance of repeatedly executed queries when persistence is enabled. Recently executed queries should see dramatic improvements. This benefit is reduced if changes accumulate while the query is inactive. Queries that use the limit() API may not always benefit, depending on the accumulated changes.
  • Changed the location of Firestore's locally stored data from the Documents folder to Library/Application Support, hiding it from users of apps that share their files with the iOS Files app. Important: After a user's data is migrated, downgrading to an older version of the SDK will cause the user to appear to lose data, since older versions of the SDK can't read data from the new location (#843).

Please make sure your GoogleServices-Info.plist (or FirebaseOptions if you configure Firebase in code) is up to date. The file and settings can be downloaded from the Firebase Console (#4683).

Version 6.15.0 - January 14, 2020

  • Reorganized directory structure.
  • The following SDKs introduce a new transitive dependency on the Firebase installations API:

  • Added new APIs that are more consistent with other Firebase SDKs and more intuitive to use. The new APIs also give your users more control over how you collect their data.
  • Removed the Fabric API Key. Now, Crashlytics uses the GoogleService-Info.plist file to associate your app with your project. If you linked your app from Fabric and want to upgrade to the new SDK, remove the Fabric API key from your run and upload-symbols scripts. We also recommend removing the Fabric section from your app's Info.plist (when you upgrade, Crashlytics uses the new configuration you set up in Firebase).

Firebase installations service

  • Firebase installations service is an infrastructure service for Firebase services that creates unique identifiers and authentication tokens for Firebase clients (called "Firebase installations") enabling Firebase Targeting, i.e. interoperation between Firebase services.
  • The Firebase installations SDK introduces the Firebase installations API. Developers that use API key restrictions may experience blocked requests (https://stackoverflow.com/questions/58495985/). This problem can be mitigated by following the instructions found here.

FCM

  • Fix component startup time (#4137).

Performance Monitoring

  • Fixed issue related to app start trace being insanely long. #934
  • Fixed issues related to monitoring NSURLSession based network requests where some of the requests were not monitored after iOS 13.

Remote Config

  • Fix the return status code when app is offline (#4100).
  • Internal code cleanup (#4297, #4403, #4379).

Version 6.13.0 Patch Release - November 19, 2019

This release does not include updates to the zip file or Carthage distributions.

Cloud Firestore

  • Firestore no longer loads its TLS certificates from a bundle, which fixes crashes at startup when the bundle can't be loaded. This fixes a specific case where the bundle couldn't be loaded due to non-ASCII characters in the application name. If you're manually tracking dependencies, you can now remove gRPCCertificates-Cpp.bundle from your build (#3951).

Version 6.13.0 - November 14, 2019

  • Updated the Firebase Core minor version to prepare for an upcoming Firebase pod open source.

Analytics

  • Fixed crash after completed in-app purchase (#4176).

Authentication

  • Added support for Sign-in with Apple (#4183).

Cloud Firestore

  • Removed Firestore's dependency on the Protobuf CocoaPod. If you're manually tracking dependencies, you may be able to remove it from your build (note, however, that other Firebase components may still require it).
  • Added a dependency on the abseil CocoaPod. If you're manually tracking dependencies, you need to add it to your build.

FCM

  • Moved message queue delete operation to a serial queue to avoid race conditions in unit tests (#4236).

Performance Monitoring

Remote Config

  • Remote Config no longer re-activates the current config on fetch if it receives no changes from the backend. (#4260)

Cloud Storage

  • Fixed a -Wunused-property-ivar violation (#4281).

Version 6.12.0 - November 5, 2019

  • The zip file distributions are now built with Xcode 11.0. The zip file distribution no longer support Xcode 10.3 and below. The Carthage distribution is still built with Xcode 10.1 and is planned to update to Xcode 11.0 in the next release. As a workaround for (#3791), Carthage users can integrate GoogleSignIn.framework from the (zip distribution).

Analytics

  • Updated podspec to depend on exact nanopb version.

Realtime Database

  • Addressed an issue with NSDecimalNumber case that prevented decimals with high precision to be stored correctly in our persistence layer (#4108).

Cloud Firestore

  • Added whereField(_:in:) and whereField(_:arrayContainsAny:) query operators. whereField(_:in:) finds documents where a specified field’s value is IN a specified array. whereField(_:arrayContainsAny:) finds documents where a specified field is an array and contains ANY element of a specified array.
  • Firestore SDK now uses Nanopb rather than the Objective-C Protobuf library for parsing protos. This change does not affect visible behavior of the SDK in any way. While we don't anticipate any issues, please report any issues with network behavior or persistence that you experience.

InstanceID

  • Fixed a crash in checkTokenRefreshPolicyWithIID: and ensure tokenWithAuthorizedEntity:scope:options:handler method is refreshing token if token is stale (#4167).
  • Updated deprecated keychain access level (#4172).

FCM

  • Moved reliable message queue database operation off main thread (#4053).

  • Fixed storyboard layout error in Xcode 11 (#3748).

FCM

  • Updated Protobuf version to fix warnings in Xcode.

ML Kit for Firebase

  • An enhanced version of barcode scanner with better speed and accuracy.
  • Breaking change: Updated ModelManager with the following API changes:
    • Added modelManager(app:) for a custom Firebase app. Note that download management for custom Firebase apps is currently only supported for the Translate SDK.
    • Removed the RemoteModel and LocalModel registration APIs. You no longer need to register models before using them.
    • Added a model download conditions parameter in the download(_:conditions) API to make it easier to tie the conditions to specific download requests. You can fully control when to download a model for the first time and when to check for model updates via this API.
    • Updated isRemoteModelDownloaded(_:) to isModelDownloaded(_:).
    • Added deleteDownloadedModel(_:completion:) to delete downloaded models to provide you with more flexibility for managing disk space on your user's devices.
    • Removed deleteDownloadedTranslateModel(_:completion)
    • Updated the availableTranslateModelsWithApp(app:) method to a downloadedTranslateModels property.
  • Breaking change: RemoteModel and LocalModel initializers have been disabled. New subclasses have been added for AutoML, Custom, and Translate SDKs. Use the initializers for those subclasses to create instances of remote and local models. initialConditions and updateConditions are no longer needed for initializing a remote model. You can specify the download condition when calling download(_:conditions:) of the ModelManager.
  • Added CustomRemoteModel and CustomLocalModel as instantiable subclasses of RemoteModel and LocalModel classes, respectively.
  • Breaking change: Updated the initializers for ModelInterpreter and removed the ModelOptions class. The ModelInterpreter can be initialized with either a CustomRemoteModel or CustomLocalModel, but not both.
  • Breaking change: Implicit model downloading is no longer available through the ModelInterpreter. You must invoke the ModelManager's download(_:conditions:) API to download CustomRemoteModels. Please see the Model Interpreter QuickStart app for an example of how to download CustomRemoteModels.
  • Added AutoMLRemoteModel and AutoMLLocalModel as instantiable subclasses of RemoteModel and LocalModel classes, respectively.
  • Breaking change: Updated the initializers for VisionOnDeviceAutoMLImageLabelerOptions. The VisionOnDeviceAutoMLImageLabelerOptions can be initialized with either an AutoMLRemoteModel or AutoMLLocalModel, but not both.
  • Breaking change: Implicit model downloading is no longer available through the VisionOnDeviceAutoMLImageLabeler. You must invoke the ModelManager's download(_:conditions:) API to download AutoMLRemoteModels. Please see the Vision QuickStart app for an example of how to download AutoMLRemoteModels.
  • Breaking change: Updated the initializers for TranslateRemoteModel. A TranslateRemoteModel can only be initialized with a TranslateLanguage. Download conditions are now passed to ModelManager's download(_:conditions:) API, and custom Firebase apps are supported through ModelManager's modelManager(app:) API.
  • Breaking change: On-device text recognition API for iOS no longer supports i386 architecture, but continues to support x86_64, arm64, and armv7 architectures.

Performance Monitoring

  • Added a waitForPendingWrites() method to FIRFirestore class which allows users to wait on a promise that resolves when all pending writes are acknowledged by the Firestore backend.
  • Added a terminate() method to FIRFirestore which terminates the instance, releasing any held resources. Once it completes, you can optionally call clearPersistence() to wipe persisted Firestore data from disk.

Firebase In-App Messaging

  • Undeprecated initializer for FIRInAppMessagingAction so it can be used going forward in custom UI display (#3545).

InstanceID

  • Moved two headers from internal to private for Remote Config open sourcing (#3621).
