A Swift kernel for Google Colaboratory that enables Swift programming in the browser with GPU support for machine learning.
Swift-Colab is a Jupyter kernel that enables developers to write and execute Swift code in Google Colaboratory notebooks. It provides a browser-based Swift programming environment with support for GPU acceleration, package management, and integration with machine learning libraries like Swift for TensorFlow. The project was created to fill the gap after Google discontinued built-in Swift support in Colab.
Swift developers, educators, and machine learning practitioners who want to use Swift in an interactive notebook environment, especially those working on Chromebooks, tablets, or other devices without a full desktop development setup.
It offers a quick-start, browser-accessible Swift environment with free GPU resources, making it ideal for prototyping, education, and machine learning experiments without local setup. As the maintained successor to swift-jupyter, it ensures ongoing Swift support in Colab.
Swift kernel for Google Colaboratory
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Starts in about 30 seconds on any device with a browser, specifically targeting Chromebooks and tablets as noted in the README, eliminating local setup.
Provides access to free NVIDIA GPUs for machine learning tasks directly from Swift, leveraging Colab's cloud resources without cost.
Uses %install commands with caching to speed up subsequent builds, reducing wait times for package installations after the first compile.
Runs legacy Swift Jupyter notebooks from the Swift for TensorFlow era with minimal modifications, preserving existing educational and experimental work.
Suffers from a major bug due to Colab updates, requiring workarounds like downgrading to Swift 5.6.2, as admitted in the README, leading to unreliable sessions.
Swift for TensorFlow integration relies on an outdated TensorFlow 2.4 binary and complex setup, with compilation taking 3 minutes and potential compatibility issues.
Depends on Google Colab's free tier, which has time limits causing automatic restarts and requires manual intervention to maintain Swift mode, disrupting workflow.
