regex - Xcode 6 doesn't recognize 1, 2, # patterns anymore?

Question

In Xcode 5 I could do search-and-replaces like this:

(regex)
   find: [([a-zA-Z]+) ([a-zA-Z]+)]
replace: .1

In order to switch from syntax like [ble bla] to ble.bla. But when I do these sorts of searches in Xcode 6, I now turn [ble bla] into 0.1.

How do I use groups from the find as part of the replace?

Answer 1

Use $# instead of # to refer to the groups.

(regex)
   find: [([a-zA-Z]+) ([a-zA-Z]+)]
replace: $0.$1
