iOS Google ML Kit Translate - .NET Binding

This repository provides a .NET iOS binding for the GoogleMLKit/Translate library, enabling the use of Google ML Kit's translation capabilities in .NET iOS applications.

Features

• Language Translation: Translate text between supported languages.

Limitations

iOS Simulator Architecture Issue

Due to an issue with the Google ML Kit library not supporting the arm64 architecture for iOS simulators, you need to configure your project to build for the x64 architecture when targeting the iOS simulator. This is necessary to avoid build errors when running the application on an iOS simulator.

For more details on this issue, you can refer to the official issue on the Google issue tracker: Issue 178965151 - iOS Simulator arm64 not supported.

Configuring the Project for iOS Simulator

To ensure that your project builds correctly for the iOS simulator, add the following setting to your .csproj file:

<PropertyGroup>
  
  <ForceSimulatorX64ArchitectureInIDE>true</ForceSimulatorX64ArchitectureInIDE>
</PropertyGroup>

Prerequisites

• Xcode: Ensure you have the latest version of Xcode installed.
• .NET 8.0 or later: This binding is designed for use with .NET 8.0 or later.
• Cocoapods: Used to download Google ML Kit for translation and its depedencies.

Steps to Generate the NuGet Package

1. Prepare the Native Library

The binding project depends on the native GoogleMLKit/Translate library. You must build the xcframeworks from the native project using CocoaPods and a custom build script.

a. Navigate to the Native Project Directory

Open your terminal and navigate to the native/EngageMLKit directory:

cd native/EngageMLKit

b. Install CocoaPods Dependencies

Run the following command to install the required dependencies:

pod install

c. Build the xcframework

Execute the build.sh script to generate the xcframework:

sh ./build.sh

The generated xcframework will be available in the native/EngageMLKit/build directory.

2. Test API bindings

Open MLKitBindingTestApp.sln and launch on device/simulator

Usage

  var stringSource = "Hello how are you, My name is Yana and I am 19 years old?"
  var options = new MLKTranslatorOptions(Constants.MLKTranslateLanguageEnglish, Constants.MLKTranslateLanguageUkrainian);
  MLKTranslatorDownloadModelIfNeededCallback callback = (error) => {
      if (error != null)
      {
          Console.WriteLine($"Error: {error}");
          return;
      }
      
      Console.WriteLine("Downloaded model");
      translator.TranslateText(stringSource, (result, error) => {
          if (error != null)
          {
              Console.WriteLine($"Error: {error}");
              return;
          }
          
          Console.WriteLine($"Result: {result}");
      });
  };
  translator = MLKTranslator.TranslatorWithOptions(options);
  translator.DownloadModelIfNeededWithCompletion(callback);
