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:

```swift
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:

```swift
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](https://swift.org/download/#snapshots). 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.
