firebase-ios-sdk/FirebaseAI/CHANGELOG.md

12.5.0

• [fixed] Fixed a nanoseconds parsing issue in the Live API when receiving a LiveServerGoingAwayNotice message. (#15410)
• [feature] Added support for sending video frames with the Live API via the sendVideoRealtime method on LiveSession. (#15432)

12.4.0

• [feature] Added support for the URL context tool, which allows the model to access content from provided public web URLs to inform and enhance its responses. (#15221)
• [changed] Using Firebase AI Logic with the Gemini Developer API is now Generally Available (GA).
• [changed] Using Firebase AI Logic with the Imagen generation APIs is now Generally Available (GA).
• [feature] Added support for the Live API, which allows bidirectional communication with the model in realtime.

To get started with the Live API, see the Firebase docs on Bidirectional streaming using the Gemini Live API. (#15309)

12.3.0

• [feature] Added support for the Code Execution tool, which enables the model to generate and run code to perform complex tasks like solving mathematical equations or visualizing data. (#15280)
• [fixed] Fixed a decoding error when generating images with the gemini-2.5-flash-image-preview model using generateContentStream or sendMessageStream with the Gemini Developer API. (#15262)

12.2.0

• [feature] Added support for returning thought summaries, which are synthesized versions of a model's internal reasoning process. (#15096)
• [feature] Added support for limited-use tokens with Firebase App Check. These limited-use tokens are required for an upcoming optional feature called replay protection. We recommend enabling the usage of limited-use tokens now so that when replay protection becomes available, you can enable it sooner because more of your users will be on versions of your app that send limited-use tokens. (#15099)

12.0.0

• [feature] Added support for Grounding with Google Search. (#15014)
• [removed] Removed CountTokensResponse.totalBillableCharacters which was deprecated in 11.15.0. Use totalTokens instead. (#15056)

11.15.0

• [fixed] Fixed Sendable warnings introduced in the Xcode 26 beta. (#14947)
• [added] Added support for setting title in string, number and array Schema types. (#14971)
• [added] Added support for configuring the "thinking" budget when using Gemini 2.5 series models. (#14909)
• [changed] Deprecated CountTokensResponse.totalBillableCharacters; use totalTokens instead. Gemini 2.0 series models and newer are always billed by token count. (#14934)

11.13.0

• [feature] Initial release of the Firebase AI Logic SDK (FirebaseAI). This SDK replaces the previous Vertex AI in Firebase SDK (FirebaseVertexAI) to accommodate the evolving set of supported features and services.
  • The new Firebase AI Logic SDK provides preview support for the Gemini Developer API, including its free tier offering.
  • Using the Firebase AI Logic SDK with the Vertex AI Gemini API is still generally available (GA).

To start using the new SDK, import the FirebaseAI module and use the top-level FirebaseAI class. See details in the migration guide .

• [fixed] Fixed ModalityTokenCount decoding when the tokenCount field is omitted; this occurs when the count is 0. (#14745)
• [fixed] Fixed Candidate decoding when SafetyRating values are missing a category or probability; this may occur when using Gemini for image generation. (#14817)

11.12.0

• [added] Public Preview: Added support for specifying response modalities in GenerationConfig. This includes public experimental support for image generation using Gemini 2.0 Flash (gemini-2.0-flash-exp). (#14658)
  
  Note: This feature is in Public Preview and relies on experimental models, which means that it is not subject to any SLA or deprecation policy and could change in backwards-incompatible ways.
• [added] Added support for more Schema fields: minItems/maxItems (array size limits), title (schema name), minimum/maximum (numeric ranges), anyOf (select from sub-schemas), and propertyOrdering (JSON key order). (#14647)
• [fixed] Fixed an issue where network requests would fail in the iOS 18.4 simulator due to a URLSession bug introduced in Xcode 16.3. (#14677)

11.11.0

• [added] Emits a warning when attempting to use an incompatible model with GenerativeModel or ImagenModel. (#14610)

11.10.0

• [feature] The Vertex AI SDK no longer requires @preconcurrency when imported in Swift 6.
• [feature] The Vertex AI Sample App now includes an image generation example.
• [changed] The Vertex AI Sample App is now part of the quickstart-ios repo.
• [changed] The role in system instructions is now ignored; no code changes are required. (#14558)

11.9.0

• [feature] Public Preview: Added support for generating images using the Imagen 3 models.
  
  Note: This feature is in Public Preview, which means that it is not subject to any SLA or deprecation policy and could change in backwards-incompatible ways.
• [feature] Added support for modality-based token count. (#14406)

11.6.0

• [changed] The token counts from GenerativeModel.countTokens(...) now include tokens from the schema for JSON output and function calling; reported token counts will now be higher if using these features.

11.5.0

• [fixed] Fixed an issue where VertexAI.vertexAI(app: app1) and VertexAI.vertexAI(app: app2) would return the same instance if their location was the same, including the default us-central1. (#14007)
• [changed] Removed format: "double" in Schema.double() since double-precision accuracy isn't enforced by the model; continue using the Swift Double type when decoding data produced with this schema. (#13990)

11.4.0

• [feature] Vertex AI in Firebase is now Generally Available (GA) and can be used in production apps. (#13725)
  
  Use the Vertex AI in Firebase library to call the Vertex AI Gemini API directly from your app. This client library is built specifically for use with Swift apps, offering security options against unauthorized clients as well as integrations with other Firebase services.
  
  Note: Vertex AI in Firebase is currently only available in Swift Package Manager and CocoaPods. Stay tuned for the next release for the Zip and Carthage distributions.

  • If you used the preview version of the library, visit the migration guide to learn about some important updates.
• [changed] Breaking Change: The HarmCategory enum is no longer nested inside the SafetySetting struct and the unspecified case has been removed. (#13686)
• [changed] Breaking Change: The BlockThreshold enum in SafetySetting has been renamed to HarmBlockThreshold. (#13696)
• [changed] Breaking Change: The unspecified case has been removed from the FinishReason, BlockReason and HarmProbability enums; this scenario is now handled by the existing unknown case. (#13699)
• [changed] Breaking Change: The property citationSources of CitationMetadata has been renamed to citations. (#13702)
• [changed] Breaking Change: The initializer for Schema is now internal; use the new type methods Schema.string(...), Schema.object(...), etc., instead. (#13852)
• [changed] Breaking Change: The initializer for FunctionDeclaration now accepts an array of optional parameters instead of a list of required parameters; if a parameter is not listed as optional it is assumed to be required. (#13616)
• [changed] Breaking Change: CountTokensResponse.totalBillableCharacters is now optional (Int?); it may be null in cases such as when a GenerateContentRequest contains only images or other non-text content. (#13721)
• [changed] Breaking Change: The ImageConversionError enum is no longer public; image conversion errors are still reported as GenerateContentError.promptImageContentError. (#13735)
• [changed] Breaking Change: The CountTokensError enum has been removed; errors occurring in GenerativeModel.countTokens(...) are now thrown directly instead of being wrapped in a CountTokensError.internalError. (#13736)
• [changed] Breaking Change: The enum ModelContent.Part has been replaced with a protocol named Part to avoid future breaking changes with new part types. The new types TextPart and FunctionCallPart may be received when generating content; additionally the types InlineDataPart, FileDataPart and FunctionResponsePart may be provided as input. (#13767)
• [changed] Breaking Change: All initializers for ModelContent now require the label parts:. (#13832)
• [changed] Breaking Change: HarmCategory, HarmProbability, and FinishReason are now structs instead of enums types and the unknown cases have been removed; in a switch statement, use the default: case to cover unknown or unhandled values. (#13728, #13854, #13860)
• [changed] Breaking Change: The Tool initializer is now internal; use the new type method functionDeclarations(_:) to create a Tool for function calling. (#13873)
• [changed] Breaking Change: The FunctionCallingConfig initializer and Mode enum are now internal; use one of the new type methods auto(), any(allowedFunctionNames:), or none() to create a config. (#13873)
• [changed] Breaking Change: The CandidateResponse type is now named Candidate. (#13897)
• [changed] Breaking Change: The minimum deployment target for the SDK is now macOS 12.0; all other platform minimums remain the same at iOS 15.0, macCatalyst 15.0, tvOS 15.0, and watchOS 8.0. (#13903)
• [changed] Breaking Change: All of the public properties of GenerationConfig are now internal; they all remain configurable in the initializer. (#13904)
• [changed] The default request timeout is now 180 seconds instead of the platform-default value of 60 seconds for a URLRequest; this timeout may still be customized in RequestOptions. (#13722)
• [changed] The response from GenerativeModel.countTokens(...) now includes systemInstruction, tools and generationConfig in the totalTokens and totalBillableCharacters counts, where applicable. (#13813)
• [added] Added a new HarmCategory .civicIntegrity for filtering content that may be used to harm civic integrity. (#13728)
• [added] Added probabilityScore, severity and severityScore in SafetyRating to provide more fine-grained detail on blocked responses. (#13875)
• [added] Added a new HarmBlockThreshold .off, which turns off the safety filter. (#13863)
• [added] Added an optional HarmBlockMethod parameter method in SafetySetting that configures whether responses are blocked based on the probability and/or severity of content being in a HarmCategory. (#13876)
• [added] Added new FinishReason values .blocklist, .prohibitedContent, .spii and .malformedFunctionCall that may be reported. (#13860)
• [added] Added new BlockReason values .blocklist and .prohibitedContent that may be reported when a prompt is blocked. (#13861)
• [added] Added the PromptFeedback property blockReasonMessage that may be provided alongside the blockReason. (#13891)
• [added] Added an optional publicationDate property that may be provided in Citation. (#13893)
• [added] Added presencePenalty and frequencyPenalty parameters to GenerationConfig. (#13899)

11.3.0

• [added] Added Decodable conformance for FunctionResponse. (#13606)
• [changed] Breaking Change: Reverted refactor of GenerativeModel and Chat as Swift actors (#13545) introduced in 11.2; The methods generateContentStream, startChat and sendMessageStream no longer need to be called with await. (#13703)

11.2.0

• [fixed] Resolved a decoding error for citations without a uri and added support for decoding title fields, which were previously ignored. (#13518)
• [changed] Breaking Change: The methods for starting streaming requests (generateContentStream and sendMessageStream) are now throwing and asynchronous and must be called with try await. (#13545, #13573)
• [changed] Breaking Change: Creating a chat instance (startChat) is now asynchronous and must be called with await. (#13545)
• [changed] Breaking Change: The source image in the ImageConversionError.couldNotConvertToJPEG error case is now an enum value instead of the Any type. (#13575)
• [added] Added support for specifying a JSON responseSchema in GenerationConfig; see control generated output for more details. (#13576)
