How do I unwrap optionals safely with if let?

In Swift, unwrapping optionals safely can be done using the `if let` statement. This approach allows you to check whether an optional contains a value and, if it does, assign that value to a new constant. This prevents runtime errors that can occur when trying to use nil values.

Here’s a simple example of using `if let` for optional unwrapping:

let optionalString: String? = "Hello, Swift!" if let unwrappedString = optionalString { print(unwrappedString) // Output: Hello, Swift! } else { print("optionalString was nil") }
