How to find unused code in Xcode 7?

I have seen this question, but the answer doesn't seem to be valid in Xcode 7. At least I can't find it.

Can anyone tell me where can I tell the compiler to notify me about unused functions/parameters/values ?

Xcode has a number of settings you can enable to warn you about things like unused functions, parameters, and values.

You can also easily enable strict warnings by setting your Other Warning Flags to -Wall -Wextra -Weverything.

Another option for detecting unused code is by using Code Coverage.
