This document is intended to be the canonical source of truth for things like supported toolchain versions for building Swift. If you find a requirement that this doc does not capture, please submit an issue on github.
This document is intended to be relative to the branch in which it is found. It is guaranteed that requirements will change over time for the development branch, but release branches of Swift should not change.
Some of the Swift development helper scripts rely on a fairly up-to-date GNU tools environment, so most recent Linux distros should work just fine out-of-the-box.
Swift is written in Google’s GO programming language. Currently, Swift is developed and tested on go 1.8.3. If you haven’t set up a GO development environment, please follow these instructions to install GO.
$ go get github.com/appscode/swift $ cd $(go env GOPATH)/src/github.com/appscode/swift
To install various dev tools for Swift, run the following command:
# setting up dependencies for compiling protobufs... $ ./_proto/hack/builddeps.sh # setting up dependencies for compiling swift... $ ./hack/builddeps.sh
Please note that this replaces various tools with specific versions needed to compile swift. You can find the full list [here](https://github.com/appscode/swift/blob/0.9.0/_proto/hack/builddeps.sh#L54.
$ ./hack/make.py $ swift version
Swift uses Glide to manage dependencies. Dependencies are already checked in the
If you want to update/add dependencies, run:
$ glide slow
To build and push your custom Docker image, follow the steps below. To release a new version of Swift, please follow the release guide.
# Build Docker image $ ./hack/docker/setup.sh; ./hack/docker/setup.sh push # Add docker tag for your repository $ docker tag appscode/swift:<tag> <image>:<tag> # Push Image $ docker push <image>:<tag>
