When using capture groups in regular expressions, those groups should be interpolatable in the replace text using $1, $2, ..., $n. Xcode 9 does not interpolate them in the source editor's search/replace (⌘ ⌥ F). The Find navigator's replace does still perform the interpolation.

Steps to Reproduce:
Try to use a capture group with regular expression search/replace in the source editor (not the Find navigator).

Expected Results:
Expect the captured matching patterns to be written back into the source editor upon replacing.

Observed Results:
The capture group interpolator symbols ($1, $2, etc) are written in place of the matched patterns.
