start publishing time let cancellableTimerPublisher = timerPublisher. } // start manually let timerPublisher = Timer. You can use Combine to get periodic time updates through a publisher: var cancellable: An圜ancellable?Ĭancellable = Timer. These are the ones that I used mostly to simplify my code: There are just a few built-in publishers in the Foundation framework, but I think the number will grow rapidly. Since there are some great articles & books about using Combine, I decided to gather only those practical examples and patterns here that I use on a regular basis. You will see how amazing it is to work with this framework, so I if you are still not convinced, it's time to. Learn Combine and be prepared to flip the switch, if the time comes, but if you are just starting a new project and you can go with iOS13+ then I suggest to go with Combine only. My advice is to stay with your current favorite solution for about one year (but only if you are happy with it). Oh, by the way you might ask the question. This is one of the biggest updates since the completely revamped GCD framework API in Swift. This is the future of aysnc programming on Apple plaftorms, and it's brighter than it was ever before. Built-in memory management - no more bags to carry on.Multithreading - you don't have to worry about it (that much).Cancellation support - it was always an issue with Promises.Multi-platform - except on linux, we're good with SwiftNIO's approach.Composable components - composition over inheritance & reusability.

Declarative syntax - easier to read and maintain code.Simplified asynchronous code - no more callback hells.Do you remember iOS6? Yeah, next up: iOS14!!!Īnyway, there are a bunch of goodies that Combine will bring you: My only concern is that you can only use it if you are targeting iOS13 or above, but this will fade away (in a blink) with time, just like it was with collection and stack views. I believe that Combine is a huge leap forward and everyone should learn it.
Staying with our current example, the sink method is a built-in function that can connect a publisher to a subscriber. Since we can publish all sort of things, we can assume that on the other end of the publisher chain, there will be some sort of object that's going to use our final result. The final member of the Combine family is the Subscriber. By using operators you can chain a bunch of publishers together, this gives us that nice declarative syntax that I mentioned before. They are special functional methods and they always return a Publisher. Moving forward to the next few lines we can see examples of various Operator functions ( map, decode, replaceError, ereaseToAnyPublisher). The most important thing here is the new dataTaskPublisher method. 🤔 private var cancellable: An圜ancellable? Allow me to grab one example and paste it here again, I'll show you why. I already made a brief networking example of using Combine, which is good if you're just looking for a simple code snippet to simplify your URLSession requests. Combine is the "native" Swift implementation of this programming paradigm, made by Apple. So basically you can process and transform values over time using functional methods like map, flatMap, etc. It's a special kind of functional programming, where you are working with async streams of values. Functional reactive programming ( FRP) is a special paradigm used to deal with asynchronous code. In other words, it allows you to write functional reactive code in a declarative way using Swift.
