How do you handle optionals and implement error handling in Swift?

In Swift, optionals and error handling are powerful features that help developers write safer and more robust code. They enable you to handle situations where a value may be missing or when an error occurs during the execution of your program. Let's explore how optionals and error handling are handled in Swift: 1. Optionals: * Handling Optionals: Optionals represent the possibility of a value being present or absent. They are widely used in Swift to handle situations where a variable or property may have no value. You can use optionals to safely unwrap and access the underlying value or check for its absence. * Optional Binding: Optional binding provides a safe way to check if an optional contains a value and assign it to a new variable or constant within a conditional block. It helps prevent force unwrapping and handles the scenario where the optional is nil. * Optional Chaining: Optional chaining allows you to chai....
