Using Result type with async/await

[mayoff (Rob Mayoff)]

@gahms

switch result {
    case .success(let products):
        // Handle success
    case .failure(let error):
        // Handle error
}

but now we are back at nesting. If we want to call another api inside the success we are nested one level more. For each call, the nesting increases.

You don't have to nest the success handling.

let products: [Product]
switch result {
    case .success(let p):
        products = p
    case .failure(let error):
        // handle error
        return
}

// handle success
