what is the meaning of life in swift

In Swift, we can't answer the age-old philosophical question of what is the meaning of life. However, we can create a program that prompts the user for their interpretation of the meaning of life and prints it out.

main.swift
print("What is the meaning of life?")
if let meaningOfLife = readLine() {
    print("Your interpretation of the meaning of life is: \(meaningOfLife)")
}

This program first prompts the user with the question "What is the meaning of life?" and waits for a response which is assigned to the meaningOfLife variable using optional binding. The program then prints the user's interpretation of the meaning of life. Running this program in a Swift Playground or on the command line will allow the user to input their own answer to this existential question.
