    Generative AI Swift

    This SDK is now deprecated, use the unified Firebase SDK

    ...It includes a sample app that showcases a chat interface, where users send messages and receive responses streamed in real time, with UI updates as tokens arrive. The code also handles request queuing, cancellation, and retry logic, giving developers a realistic foundation rather than a minimalist “hello world.” Despite its deprecated label, the repo remains valuable for developers who want to see how a native Swift integration might be structured before migrating to newer SDKs. Maintainability is emphasized: modular layers separate networking, prompt handling, and UI logic, making adaptation easier when switching to updated APIs.

    A modern cmake starter project for C++ with a complete build lifecycle

    ...The C++ ecosystem is getting better but is still very far away from other ecosystems such as JavaScript, or even Rust. It's certainly easy to use CMake, a compiler and vscode to start a hello world project, but as soon as you start having multiple modules, with third party dependencies, testing, coverage, and other development things that a professional quality project needs, you start wasting hours and hours troubleshooting and configuring until you make it work. This starter project solves most of your problems, using the best practices for C++ development and modern CMake and allows you to get started in minutes rather than days.
