Swift language added to Redis Course
Hmm, I'm struggling to get caching working here. Even after running swift build inside the dockerfile, compile times are 60s+.
This'd make our test runners practically unusable - the longest I've seen for other languages is ~10s (Haskell, I think).
I suspect that we might need to do something hacky like we do for Rust here: https://github.com/codecrafters-io/build-your-own-redis/blob/c5b3c42749805e2013250bde363f0c46841afa2d/dockerfiles/rust-1.76.Dockerfile#L7-L21.
@bobvoorneveld ideas? I've pushed up one commit which was an attempt to incremental compilation working.
I haven't looked too deeply into the build system, but it sounds like you're having a similar problem to the one in this thread I found in the swift community, and this particular comment has a suggestion for how to write a Dockerfile for incremental builds. I'm not sure if you've already seen this or not, but I thought it might help.
@abstractJohn, I'll have a look. Wasn't succesful when trying to get intermediate builds, which is a shame. I'll give it another try!
I've tried, but I'm not familiar enough with swift + docker to get intermediate builds working. SwiftNIO is a big depencency that will create a long build time, which makes it hard to speed up compile times. I'm closing this PR, maybe someone else can create a PR in the future to make this possible. I've created a PR for Build Your Own Git and swift as an alternative, hopefully that will attract some swift developers that can help in the future.
