  • All Services: Default HTTP headers can now be set for each service.

  • All Services: The service URL parameter was moved from each init to a class property. To set a custom service URL parameter, set the class property instead of passing it as a parameter to the initializer. (For example: textToSpeech.serviceURL = "...".)

  • Credentials: Testing credentials were moved to a .swift file for convenience.

  • Language Translator: Update the default service URL for the recent release of the Language Translator service. To use an existing Language Translation service, specify a custom service URL.

  • Natural Language Classifier: Updates the trained classifier id used for testing.

  • Speech to Text: Add support for setting customization_id parameter.

  • Speech to Text: Added support for additional audio formats (AudioMediaType.MuLaw and AudioMediaType.Basic)

  • Speech to Text: Added support for the supported_features parameter of language models, which identifies whether certain additional service features are supported with any given model.

  • Speech to Text: Fix a bug where the microphone would continue recording when disconnected by the service (which also prevented the service from operating correctly when reconnecting).

  • Text to Speech: Validate the status code in the response to synthesize(). This helps to produce more meaningful error messages when using incorrect credentials with the service.

2016-09-30

The release updates the Swift 2.2 version of the iOS SDK with several bug fixes and minor changes.

  • All Services: The service URL parameter was moved from each init to a class property. To set a custom service URL parameter, set the class property instead of passing it as a parameter to the initializer. (For example: textToSpeech.serviceURL = "...".)

  • Cartfile: The Cartfile was updated to explicitly specify Swift 2.2 compatible versions of the SDK's dependencies.

  • Credentials: Testing credentials were moved to a .swift file for convenience.

  • Language Translator: Update the default service URL for the recent release of the Language Translator service. To use an existing Language Translation service, specify a custom service URL.

  • Natural Language Classifier: Updates the trained classifier id used for testing.

  • Speech to Text: Added support for additional audio formats (AudioMediaType.MuLaw and AudioMediaType.Basic)

  • Speech to Text: Added support for the supported_features parameter of language models, which identifies whether certain additional service features are supported with any given model.

  • Speech to Text: Fix a bug where the microphone would continue recording when disconnected by the service (which also prevented the service from operating correctly when reconnecting).

  • Text to Speech: Validate the status code in the response to synthesize(). This helps to produce more meaningful error messages when using incorrect credentials with the service.

Version 0.3.0

2016-05-21

The iOS-sdk version 0.3.0 has many major changes with this new release. The team worked diligently at removing many of the third party dependencies and fully embracing AlamoFire by implementing the rest-kit code.

Major updates

  • Added IBM Watson Tone Analyzer
  • Added IBM Watson Visual Recognition
  • Updated all of the code to use the new Rest-kit and removed NetworkUtils and WatsonGateway. We still have one service to convert, Alchemy Language, but we anticipate that change coming in the next minor release.
  • Removed many dependencies and reducing the total number to three. Alamofire, Freddy, and Starscream.
  • You will notice an update to the targets available and now the developer can pick and choose the services to include.

The process of migrating a service to Rest-kit required a large re-implementation of the service. As part of the reimplementation, we additionally gain:

  • More consistent coding patterns between services.
  • Better documentation.
  • Better tests.
  • Reorganized project structure to support Swift Package Manager.

In addition, the Rest-kit branch has a number of architectural changes that should make the SDK easier to maintain and easier to consume.

  • Uses Alamofire directly instead of NetworkUtils or WatsonGateway.
  • Uses Freddy instead of ObjectMapper, allowing us to better express the models.
  • Uses separate failure and success closures to avoid unwrapping optionals and enable consistent error handling. We debated as a team as to the correct approach and concluded this was the best approach for the granularity. One benefit is the user does not have to unwrap a response. It also allows for a more unified error return.
