The source code to find the natural logarithm of a given number is given below. The given program is compiled and executed successfully.

// Swift program to find the natural logarithm
// of a given number
import Swift
import Foundation
var num:Double = 5.0
var res:Double = 0.0
res = log(num)
print("Result: ",res)

\Output:

Result: 1.6094379124341003
...Program finished with exit code 0
Press ENTER to exit console.

Explanation:

In the above program, we imported a package Swift to use the print() function using the below statement,

import Swift;

To use mathematics and some standard functions, we need to import the foundation package using the below statement,

import Foundation;

Here, we created two double type variables num, res that are initialized with 5.0,0.0 respectively. Then we found the natural logarithm using the log10() function of a given number and printed the result on the console screen.
