Hi @DominatorVbN I think the current implementation is already capable of querying foreign tables, and rewriting the JS example you mentioned in Swift, it should be as follows and work as expected.

let response = try await client
  .database
  .from("countries")
  .select(columns: "name,cities(name)")
  .execute()
  .value

Can you try that within your project and let me know the result?

Hey,
Though this works, this seems like a bit too stringly typed API, can we may be try to alter it in direction where we could maybe write this query using more builder and less string format, which this PR can be a pert of, may be the implementation of the PR might not be optimal, but would like to have discussion around this.

I agree with @DominatorVbN here. The syntax to grab foreign tables seems off here. There should be a more ergonomic way.
