How can I handle errors in Swift?

In Swift, you can handle errors using the do-catch statement. You wrap your code in a do block and catch errors in the catch block.

Can you give me an example of using do-catch?

Sure! Here's a simple example:

func canThrowError() throws {
    // some code that might throw an error
}

do {
    try canThrowError()
} catch {
    print("Error: \(error)")
}

What types of errors can I throw?

You can throw any type of error that conforms to the Error protocol. You can define your own error types as well.

How do I define a custom error type?

You can define a custom error type by creating an enum that conforms to the Error protocol. For example:

enum MyError: Error {
    case somethingWentWrong
}
