structure Boolean in Swift

Boolean is a data type in Swift that represents true or false values.

Here's how to use boolean in Swift with some examples:

1. Declaring a Boolean variable:

   var isRaining: Bool = true
   

2. Comparing two values using boolean operators:

   let x: Int = 10
   let y: Int = 5
   let isGreater: Bool = x > y
   

3. Using boolean conditions in control structures:

   let isSunny: Bool = true
if isSunny {

       print("It's a sunny day!")

   } else {

       print("It's a cloudy day!")

   }

   

4. Combining multiple boolean conditions using logical operators:

   let hasMoney: Bool = true
   let hasCreditCard: Bool = false
if hasMoney && hasCreditCard {

       print("You can buy a product!")

   } else {

       print("You cannot buy a product!")

   }

   

5. Using boolean in function parameters:

   func isEven(number: Int) -> Bool {
       return number % 2 == 0
   }
let num: Int = 10

   let isNumEven: Bool = isEven(number: num)
