Hi, I'm pretty new to the swift open-source community, today I've been trying to compile swift using the readme from github, I cloned the repo via SSH and ran update-checkout --clone-with-ssh and I have Xcode 12 beta 3 installed on macOS 10.15. I would like to use xcode to view/edit code, however when I run the utils/build-script --release-debuginfo --xcode I get this error:

Can someone guide me in the right direction with this error? Help would be greatly appreciated, thanks!
You might need to:
I haven't used the --xcode option recently. Instead, I created an empty xcworkspace (File → New → Workspace) inside the "swift-source" directory, and added a folder reference (File → Add Files…) for each project of interest (currently just the "swift" directory).
To build and test, I use the command line:
utils/build-script --reconfigure --release-debuginfo --test
If there are errors, due to changing CMake or Xcode versions, try adding the --clean option.
Thank you, I ended up using the xcode workspaces like you stated.
I've just built with Xcode 12 beta 3 (and CMake 3.17.0, on macOS 10.15.6) so there's no need to downgrade to beta 1.

When trying to build with Xcode 12b3, it tries to build for arm64 for some reason. I've found this issue in Cmake - Xcode 12 Universal Beta default architecture selection (#20893) · Issues · CMake / CMake · GitLab and added --extra-cmake-options="-DCMAKE_OSX_ARCHITECTURES=x86_64". This worked for Cmark and LLVM, but Swift itself still builds for arm64 and fails when linking with LLVM.

Same thing here, I had to downgrade to Xcode 12 beta 2 when building with Ninja.
CMake 3.18.1 is now available for download. It includes a fix for the above issue, where an architecture was selected arbitrarily.
