I have multiple versions of Xcode installed: Max: A lot of the guys who contribute to RxSwift say you should live and breath RxSwift from the day one your project happens. Thanks for the reply, it's much appreciated! This is the same behavior as … Tagged with swift. I think the real question here is what is the definition of RxSwift project. My understanding of merge is that it emits items even if one of the observables involved is completely empty (in other words, they are not dependent on each other). Until then, maybe it would be better to temporarily do small workarounds like you've done? Every subscribe creates a retain cycle inside Rx’s logic. (I like your rx_subscribeEnabledTo suggestion BTW.). If I include this, I don't have to include 40 more functions, just 10 :). Something I liked from ReactiveCocoa 2 was the and operator, which operated on two signals sending NSNumbers wrapping BOOLs. While ReactiveX started as part of the .NET/C# ecosystem, it’s grown extremely popular with Rubyists, JavaScripters and, particularly, Java and Android developers. The biggest help I need here is actually proving that operators behave like they should in RxSwift. Sign in Successfully merging a pull request may close this issue. It will also possibly contain convenience functions that we can't live without and that provide significant value for future optimizations (I really think that variable/sharedWithCachedLastResult is that function). single errors out if the observable emits more than one item. If we don't have that clearly defined, people will be confused. If you are interested in having your favorite Combine operators in RxSwift, take a part in this issue. On the RxSwift GitHub there is an example in a file called ActivityIndicator.swift. Only the first merge (with an empty observable) performs as expected. But, that’s not realistic. This is where we'll probably have biggest discussion regarding APIs. Before that, it keeps sending combined values. no, Level of RxSwift knowledge: Right now it's just an alias for replay(1) >- refCount, but since it's probably going to be used often, having a single place where I can apply optimizations in future for everybody is valuable enough IMHO to include it there. It seems not working for me. The text was updated successfully, but these errors were encountered: I'm assuming one of the observable sequences sent error and disposed everything. I've been working with RxSwift for a few years now, and am starting to explore Combine with SwiftUI and am having some trouble trying to replicate some functionality from RxSwift in Combine. Short description of the issue: Observable.combineLatest(Collection) with an empty Collection does not complete. Introduce it selectively. We're all in this together , Sorry Ash, it wasn't my intention to shut you down. I have added new button however with rx_tap subscribe not working for button action. ... Competitor-reviews” and funneled all of my competitors app reviews to that channel, allowing me to easily see what is working and not working for the other apps in my space. GitHub is home to over 50 million developers working together to host and review code, manage projects, and build software together. I'm quite excited to see a variety of FRP libraries for iOS and OS X! The other significant... Read more » The reason why I feel it's so valuable is because it's probably the most common way of optimizing cold observables for performance. You are right that AFAIK, and/then/when have not been added to this library yet so asking for one of them makes a lot of sense. I'm still setting up my new computer so I can't test this myself right now, but can't you already do something like this? It's really similar to translating math books :) I'm having this issue as well even though I am not using Carthage. Basic examples of this can be seen in example three, where events from multiple buttons are being combined to produce a count of each and an overall total, or a calculation of BMIfrom the RxJS documentation. Strange, because the merge result in the second example should always emit something if more than one notification was sent, regardless of whatever observable it is merged with. If I add boolean and operator, then I should probably add all 10 overloads for all combinations of arguments, even though it's not really realistic that somebody will be using and for 10 boolean arguments :), And what's worse, I should probably add or, and xor and possibly some others too :). This is how I see their responsibility right now. We’ll occasionally send you account related emails. Because of all of this, it will probably be a lot harder to make PRs for bigger features (like operators), but easy for bugfixes (although I'm hoping there shouldn't be many serious bugs because of all of the measures :) This has it's drawbacks, but believe me, porting those operators is tedious and exhausting work. Sometimes I'm going to not know the ReactiveX jargon that would describe my question. My understanding of merge is that it emits items even if one of the observables involved is completely empty (in other words, they are not dependent on each other). to your account. RxCocoa should contain default out of the box integration with Foundation/Cocoa/UIKit environment. So these are reasons for and against as I see them. RxSwift needs a Binder / ObserverType to bind to. Something like: Then we can also have operators like and and or. RxSwift should be the purest core of the system. Last few months were for me my personal RxSwift bootcamp. Below is my code, please let me know what I … All of the operators that enter this project should not only be thoroughly unit tested but their code validity should be proved. You can trace all events for sequence by using debug operator. Replacing single() with take(1) seems to have fixed this error for me, though frankly I am uncertain as to why, as I understand them to be the same thing. There isn't much room for being creative here. This is where consistency doesn't matter so much because this is platform specific code, but having some consistency would be good idea. At least, such is my understanding. Sign in Reason why I would want that is because if some mathematical abstraction works on so many different platforms and environments (native clients/servers/web clients), it's reasonable to assume that it will work on one more. RxSwift needs a Binder / ObserverType to bind to. Swift gives us an opportunity to do something safer with the type system.
