Hey all,
I have tried programming a Riemann Zeta Function calculator, but quickly encountered a problem, I need to calculate the Natural Logarithm (ln) of a value, but Swift seems to have no built-in solution.
Are there any solutions to this problem?

The Darwin module has several logarithm functions. Put a text file of their documentation on your desktop by pasting the following command in Terminal app:
man 3 log | col -b > ~/Desktop/log.txt
You can use these functions in Swift by importing the Foundation framework or just the Darwin module itself. For example:
import Foundation
print(log(Double(10))) // 2.30258509299405
