What is the Swift Error Protocol?

Can you explain what the Swift Error Protocol is?

The Swift Error Protocol is a protocol that defines a type for errors in Swift. It allows you to create custom error types.

How do I implement a custom error type using this protocol?

To implement a custom error type, you create a struct or enum that conforms to the Error protocol and define your error cases.

Can you give me an example of a custom error type?

Sure! Here's a simple example:

enum NetworkError: Error {
    case badURL
    case timeout
    case noData
}

How do I handle errors thrown by functions?

You can handle errors using do-catch blocks. Wrap your function call in a do block and catch the errors in the catch block.
