Has anyone tried integrating the RE2 regular expression library written in C++ into a Swift project? I'm working on a performance-critical application where regex efficiency is key, and RE2's speed looks promising. What are the best practices for bridging C++ with Swift, particularly for regex processing? Any pitfalls or gotchas to watch out for? Also, is there a notable performance gain over Swift's native regex handling? Any advice or sample code would be appreciated!
