With both our custom publisher and subscription type completed, we’re now almost finished with our new Combine-powered control event API.Are you interested in designing brochures, flyers, business cards, optical disc covers, or anything else? You don’t have to worry about templates or anything because I have a great choice for you: Swift Publisher. UIControl instance, we'll simply pass Void to our Whenever an event was triggered by the underlying additional events from being sent to it: the reference to our target to prevent any When our subscription was cancelled, we'll release Observing our property's value directly: let allItemsSubscription = list. For example, here we’re adding that sort of functionality to an item property contained within a TodoList class: class TodoList private(set) var items: īy simply adding the above annotation to our items property, we’re now able to use Combine to both observe and transform any changes to that property’s value, since any property can easily be turned into a publisher using its projected value - like this: let list = TodoList(.) However, that property wrapper can also be used outside of SwiftUI as well, and provides a way to automatically generate a publisher that emits a new value whenever a given property was changed. Perhaps the currently most common way of using Combine is through the property wrapper, which plays a really important role in SwiftUI’s overall state management system. Built-in alternativesīefore we jump into building custom publishers, however, let’s start by taking a look at a few of the built-in alternatives that Combine ships with. This week, let’s take a look at what sort of situations that might warrant a custom publisher, and a few examples of what building one could entail. Within the world of Combine, an object that emits such asynchronous values and events is called a publisher, and although the framework does ship with quite a large number of built-in publisher implementations, sometimes we might want to build our own, custom ones in order to handle specific situations. Apple’s Combine framework provides a general-purpose abstraction for asynchronous programming, by enabling various values and events to be emitted, transformed and observed over time. ![]()
