Throwing Errors in Swift

Throwing errors allows you to signal that something unexpected or problematic has occurred during the execution of your code. When a function encounters a situation it can't handle normally, it can throw an error. This error is then passed up the call stack until it's caught and handled by an appropriate error handling mechanism, preventing the program from crashing and allowing for graceful recovery or reporting of the issue.
