Adding "-cxx-interoperability-mode=default" to a simple hello world miserably fails, when "import Foundation" is used:

I see swift and swiftc are installed to /usr/bin, but almost everything else is installed to /usr/lib, which leads to odd paths like this:

/usr/lib/swift/bin/clang
/usr/lib/swift/include/SourceKit/sourcekitd.h
/usr/lib/swift/lib/swift/CoreFoundation/CFData.h
/usr/lib/swift/share/doc/swift/diagnostics/temporary-pointers.md

Shouldn't these be in /usr/share/swift and so on?

Looks like it needs to depend on Python 3.9 for the swift repl command.

$ swift repl 
/usr/lib/swift/bin/lldb: error while loading shared libraries: libpython3.9.so.1.0: cannot open shared object file: No such file or directory

I am getting:

> swift build
/usr/lib/swift/bin/swift-build: error while loading shared libraries: libxml2.so.2: cannot open shared object file: No such file or directory

I guess this needs an update after the latest libxml2 release.

edit: thanks! With swift-bin 6.1-2 and the dependency to libxml2-legacy it is working again.

I have had some success repackaging the Ubuntu binaries both for x86_64 and aarch64: https://github.com/archsink/pkgbuilds/blob/e23d84133af19fb642898a6753857f79abc80f07/swift-bin/PKGBUILD

Could probably use some more battle-testing though, I have only checked that some very simple programs compile.

Is there a chance to support aarch64? The packages provided on Swift.org for Ubuntu, Red Hat and Amazon Linux all have a binary version for aarch64. Just the CentOS version used in this AUR package unfortunately does not have one.

Would it be possible to change to a different distro package and support aarch64?

Change the libutil-linux dependency to util-linux-libs

python36 is EOL since 2021 and will likely be deleted from AUR in the near future.

Just tried the latest PKGBUILD for the 5.7.3 release [57f67ecfd981], and it looks like the download link is broken. Here's the diff to make it work:
