Day 1: Introduction to SwiftUI

Today, I learned how to store truth values using Booleans in Swift, and how to join strings together.

Examples:


        
// How to store truth with Booleans

        
let fileName = "file.jpeg"

        
print(fileName.hasSuffix(".jpeg"))

        
        
let number = 30

        
print(number.isMultiple(of: 7))

        
        
// Flip a Boolean value manually

        
var authenticated = true

        
authenticated = !authenticated

        
print(authenticated)

        
        
// Flip using the built-in toggle() function

        
authenticated.toggle()

        
print(authenticated)

        
        
// How to join strings together

        
var firstName = "Deepak"

        
var middleName = " Kumar"

        
print(firstName + middleName)

        
print(firstName + middleName + " Behera")
