Booleans in Swift: A Guide to Working with True and False

In the world of Swift programming, booleans play a crucial role. Booleans are variables that can have one of two values: true or false. They are particularly handy when working with conditional control structures like “if” statements or the ternary conditional operator.

To declare a boolean variable in Swift, you can use the Bool type. Here’s an example:

var done = false
done = true

In the above example, we first initialize the done variable with the value false. Later on, we change its value to true. This flexibility allows us to toggle the state of the boolean variable based on our program’s logic.

When using boolean variables in conditional statements, we don’t necessarily need to compare them explicitly to true or false. Instead, we can directly use them in the condition. Here’s an example:

var done = true

if done {
  // code
}

In this case, the condition if done is equivalent to if done == true. Both versions achieve the same result. It’s a matter of personal preference and readability.

By leveraging booleans in Swift, you can make your code more concise and expressive. They are a vital tool for controlling your program’s flow and enabling conditional execution. So, embrace the power of booleans and level up your Swift coding skills.
