In this tutorial video, Nick from Swiffle Thinking focuses on creating custom publishers and subscribers in Swift and SwiftUI. Building on previous videos, he emphasizes the importance of understanding these concepts. The video begins with creating a timer, which was previously done directly in the view, but this time, it will be implemented within a view model. This approach allows the view to update based on the timer. Nick plans to elevate the content by designing more advanced custom publishers and subscribers that can enhance application development. By the end of the tutorial, viewers will recognize the power and utility of these concepts in their own projects.

What is publisher in combine?

At the heart of Combine is the Publisher protocol. This protocol defines the requirements for a type to be able to transmit a sequence of values over time to one or more subscribers.

What is the difference between a publisher and a subscriber?

The provider of the information is called a publisher . Publishers supply information about a subject without needing to know anything about the applications that are interested in the information. The consumer of the information is called a subscriber .

What is Apples combine?

The Combine framework provides a declarative Swift API for processing values over time. These values can represent many kinds of asynchronous events. Combine declares publishers to expose values that can change over time, and subscribers to receive those values from the publishers.

What is publisher and subscriber in combine?

The subscriber defines an associated type, Input , to declare the type that it receives. The publisher also defines a type, Output , to declare what it produces. The publisher and subscriber both define a type, Failure , to indicate the kind of error they produce or receive.

What is the difference between subject and publisher in combine?

In Swift Combine, Publishers are a protocol describing an object which can transmit values over time. A Subject is an extended publisher which knows how to send imperatively. Neither Publisher nor Subject are concrete classes with implementation; they are both protocols.

What is the difference between share and multicast combine?

Multicast() and share() are almost the same. The difference is shared() will create subscription when the first subscription subscibed, it causes the second subscription can miss some values if it is subscribed after value emitted.

What is subscriber in combine?

In Combine, a Publisher produces elements, and a Subscriber acts on the elements it receives. However, a publisher cant send elements until the subscriber attaches and asks for them. The subscriber also controls the rate at which the publisher delivers elements, by using the Subscribers.

What is the use of combine in Swift?

What is Combine? Combine was introduced as a new framework by Apple at WWDC-2019. It provides a declarative Swift API for processing values over time. The framework can be compared to frameworks like RxSwift and ReactiveSwift (formally known as ReactiveCocoa).

What is a subject in combine?

A subject is a publisher that you can use to inject values into a stream, by calling its send(:) method. This can be useful for adapting existing imperative code to the Combine model.

What is the difference between Apple Combine and RxSwift?

RxSwift supports iOS 9 and higher, while Combine requires iOS 13 and higher. Both frameworks are available on all Apple platforms, but Combine still lacks Linux support. OpenCombine can come to the rescue in these cases, featuring the same API but with an open-source implementation and support for more platforms.
