What steps should be taken to use the @escaping attribute with a closure in a function definition?

In Swift, the @escaping attribute is used for closures that are stored and called after the function they are passed to has finished. To use @escaping, you need to:

1. Specify @escaping before the closure parameter in the function declaration.
2. This means the closure can be called later, for example, asynchronously.

Example:

func fetchData(completion: @escaping () -> Void) {
    DispatchQueue.global().async {
        // Perform an asynchronous task
        completion() // call the closure later
    }
}

Without @escaping, the compiler will not allow storing the closure for calling after the function exits.
