What are some examples of optional binding in Swift?

Optional binding in Swift allows you to safely unwrap optionals. For example, you can use if let or guard let.

Can you show me a specific example using if let?

Sure! Here's an example:

var name: String? = "Alice"
if let unwrappedName = name {
    print("Hello, \(unwrappedName)!")
} else {
    print("Name is nil")
}

What about using guard let?

Here's how you can use guard let:

func greet(name: String?) {
    guard let unwrappedName = name else {
        print("Name is nil")
        return
    }
    print("Hello, \(unwrappedName)!")
}

Are there any other ways to handle optionals?

Yes, you can also use optional chaining and the nil-coalescing operator to handle optionals in Swift.
