Error handling is a critical aspect of writing robust and reliable software applications. Swift, Apple’s powerful and modern programming language, provides a comprehensive error handling mechanism that enables developers to handle errors gracefully and effectively. In this article, we’ll explore Swift’s error handling patterns, including the try, catch, and other error-handling constructs.
Understanding Errors in Swift
In Swift, errors are represented as values conforming to the Error protocol, which is an empty protocol used to identify error types. Developers can create custom error types by defining structs, enums, or classes that adopt the Error protocol.
