Given your criteria, Go might be a good choice maybe. It has a bigger or shall we say a more "successful" backend story. Regarding Swift I am not sure how popular it is for the backend, you might not have a lot of libs for example for doing common things. Also no idea well a Swift backend performs under load. Swift is a nice language for sure, maybe if you can risk it, go for it but keep also this in mind - https://boringtechnology.club/ https://boringtechnology.club/
