Implement Flatten and Chained 🚀

Chained requests

Now you're able to run up to 10 requests one-by-one!

API.employee.all()
    .and(API.office.all())
    .and(API.car.all())
    .and(API.event.all())
    .and(API.post.all())
    .onError { error in
        print(error.description)
    }.onSuccess { employees, offices, cars, events, posts in
   // do what you want with received results!!! 🍻
}

onRequestStarted, onNetworkUnavailable, onCancellation, onNotAuthorized, onTimeout also available!
//TBD: onProgress

It is awesome! Especially for whom who not familiar or don't like reactive programming 🙂

Flatten

And if you want to run several requests one-by-one or concurrently but with just completion handler you also can do that with .flatten()

[API.employee.all(), API.office.all(), API.car.all()].flatten().onError {
    print(error.description)
}.onSuccess {
    print("flatten finished!")
}

to run them concurrently just add .concurrent(by: 3) to run by 3 at the same time
to skip errors also add .avoidCancelOnError()
to get progress add .onProgress

Hope it's cool! 😎
