Description: The keyword ‘throws’ in Swift indicates that a function can throw an error. This is part of error handling in the language, allowing developers to manage exceptional situations in a controlled manner. By declaring a function with ‘throws’, it is established that this function can generate an error that must be handled by the calling code. This promotes a safer and more predictable approach to programming, as it forces developers to consider and handle potential failures. Functions that throw errors can be called within a ‘do-catch’ block, where the function can be attempted and any errors that occur can be captured, allowing for an appropriate response to the situation. This mechanism is fundamental for creating robust and reliable applications across various programming environments, as it helps prevent unexpected errors from causing program execution failures.
