Program/Source Code:

The source code to get the cosine value of the given angle in radian is given below. The given program is compiled and executed successfully.

// Swift program to get the cosine value of 
// the given angle in radian

import Swift
import Foundation

var num:Double  = 14.234
var res:Double  = 0

res = cos(num)

print("Result: ",res)

Output:

Result:  -0.09668180163468348

...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 initialized with "14.234", "0.0". Then we found the cosine value of the specified angle in radian and printed the result on the console screen.
