take the secant of a number in swift

Here's an example code snippet in Swift to calculate the secant of a number using the math library:

main.swift
import Foundation

// Define the input number
let x = 1.5

// Calculate the secant using the math library
let secant = 1 / cos(x)

// Print the result
print("The secant of \(x) is \(secant)")

In this code, we first import the Foundation library which includes the math functions we need. We then define our input number x, and calculate the secant using the cos() function and basic arithmetic. Finally, we print the result to the console.
