The desktop's own packages are in a pacman repository. To use it on an existing Manjaro install, trust the signing key and add the repository:
curl -fsSL https://sway.manjaro.download/gpg-public-key.asc | sudo pacman-key --add -
sudo pacman-key --lsign-key A44C644D792767CED7941AFEABB2075D5F310CF8
then add to /etc/pacman.conf:
[manjaro-sway]
SigLevel = PackageRequired
Server = https://sway.manjaro.download/packages/unstable/$arch
Browse it at /packages/.
