As to your real question, what’s your high-level goal?  Swift doesn’t really do pointers to functions [1] but it does provide lots of other excellent ‘treat code as data’ features.  If you can explain more about your goal, perhaps we can direct you to a better path.

[1] At least not natively.  You can use @convention(c) to interact with C APIs that require a function pointer.
