How do I use guard statements in Swift?

Guard statements in Swift are used for early exits in functions. They help to ensure certain conditions are met before proceeding.

Can you give me an example of a guard statement?

Sure! Here's a simple example:

func processValue(_ value: Int?) {
    guard let unwrappedValue = value else {
        print("Value was nil!")
        return
    }
    print("Processing value: \(unwrappedValue)")
}

What happens if the condition in a guard statement is false?

If the condition is false, the code inside the else block is executed, and the function exits immediately.

Are guard statements better than if statements?

It depends on the context! Guard statements are great for early exits, while if statements are better for conditional logic that continues execution.
