Comment(by Ahruman):

 There is indeed a fixed path in `settings`, but it doesn’t have the same
 problem of relying on an Xcode install path. Instead, GHC requires the
 command line developer tools package, now a separate installation which
 doesn’t have the option of a custom path.

 (The approach of using `xcode-select --print-path` is still valid, and
 produces `/Applications/Xcode.app/Contents/Developer` by default under the
 new regime, but there’s no clear advantage to doing that any longer.)
