Scripts and prebuilt binaries to build and run Swift 5.4 on ARM devices like Raspberry Pi.
buildSwiftOnARM is a collection of scripts and prebuilt binaries that enable the Swift programming language to run on ARM-based devices like Raspberry Pi, Orange Pi, and other ARM boards. It solves the problem of Swift not being natively available on resource-constrained ARM hardware by providing tools to compile Swift from source or use ready-made binaries. This expands Swift's usability beyond traditional desktop and server environments into embedded and IoT contexts.
Developers working with ARM-based single-board computers (e.g., Raspberry Pi, Orange Pi, ODroid) who want to write applications in Swift for IoT, embedded systems, or educational projects. It also targets Swift enthusiasts looking to experiment with the language on low-power hardware.
Developers choose buildSwiftOnARM because it provides reliable, prebuilt Swift binaries for multiple ARM architectures and Linux distributions, saving significant time and effort compared to manual compilation. Its automated build scripts and detailed instructions lower the barrier to entry, making Swift accessible on ARM devices where official support is limited.
All you need to build Swift on a RaspberryPi or other ARM boards, updated to Swift 5.1.5
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Provides ready-to-use Swift 5.4 binaries for ARMv6, ARMv7, and aarch64 on various Linux distros like Raspbian and Ubuntu, saving hours of compilation time.
Includes scripts (clone.sh, checkoutRelease.sh, build.sh) that automate cloning, patching, and building Swift from source, simplifying the process on resource-constrained ARM devices.
Offers comprehensive guidance on setting up swap files, installing dependencies, and using tmux for background builds, making it accessible even for those new to ARM development.
Acknowledges contributors and integrates with related projects like Docker alternatives and cross-compilation toolchains, providing multiple pathways for Swift on ARM.
The README explicitly states that the Swift REPL is unavailable on ARM32 platforms, limiting interactive development and debugging capabilities.
Building from source requires configuring large swap files, external storage, and can take hours, posing a significant barrier for quick adoption.
Focuses on Swift 5.4 with no updates to newer releases, missing out on recent language features and improvements from Apple.
Depends on patches from contributors for building Swift, which may introduce stability issues compared to official Swift releases.
