This is great news - I just switched from swiftarm/swift:latest to swiftlang/swift:nightly-focal and it works like expected.

Sidenote:
As I don't want to run things as current user (not as root) I'm using something like this in my build.sh:

DOCKER_UID=$(id -u ${USER})
DOCKER_GID=$(id -g ${USER})

docker build -t swift:latest -<<EOF
FROM swiftlang/swift:nightly-focal

RUN groupadd -g $DOCKER_GID swift
RUN useradd -m -u $DOCKER_UID -g swift swift
USER swift

WORKDIR /home/swift
CMD ["/home/swift/buildandstart.sh"]
EOF

and mount a directory I use for building with the -v option of docker like this:

docker run \
        --detach --restart=always \
        -u $DOCKER_UID:$DOCKER_GID \
        --net service16 \
        --log-opt max-size=1m --log-opt max-file=2 \
        -v "$packagedir":/home/swift \
        --name "$programname" \
        swift:latest

This is great! Thank you @mishal_shah !

Do you know when these might be coming for the non-nightly "stable" builds, like swift:5.4-focal ?

It looks like the builds stopped being multi architecture about 20 days ago. Was this reverted? I was really hoping the official 5.5 release would come with ARM images.

@Bridger_Maxwell There was an issue with AArch64 automation, it's fixed now and nightly toolchain will contain the AArch64 docker images.

There are still nightly snapshot builds for AArch64 on these three linux distros. Nothing else has been promised, but I'm guessing the plan is to have linux AArch64 builds of the next Swift 5.6 release, since these builds were started during its development.
