I was trying to compile swift on a computer with ~50 GB of free disk space and about midway through the process the OS will give a low disk space alert and the build will fail with ld.gold: fatal error: bin/swift-ide-test: No space left on device. just how much disk space do I need to build swift?

Omitting the tiny projects, my Linux Ninja-RelWithDebInfoAssert build is
33G public/build/Ninja-RelWithDebInfoAssert/llvm-linux-x86_64
37G public/build/Ninja-RelWithDebInfoAssert/swift-linux-x86_64
133M public/build/Ninja-RelWithDebInfoAssert/llbuild-linux-x86_64
213M public/build/Ninja-RelWithDebInfoAssert/swiftpm-linux-x86_64
133M public/build/Ninja-RelWithDebInfoAssert/foundation-linux-x86_64
----
70G public/build/Ninja-RelWithDebInfoAssert
right now. :-/ I've heard it's a lot less if you compile without debug info. (It's about half that on macOS, which doesn't copy debug info around as much.)

This 70GB figure shows up in README.md as well:
Getting Started
These instructions give the most direct path to a working Swift development environment. To build from source you will need about 2 GB of disk space for the source code and up to 70 GB of disk space for the build artifacts with full debugging.
