The final note is that in this particular situation Combine doesn't give you any guarantees as to what the ordering of publishing of hasZero and negatives. Later, the -10 gets to hasZero itself and as per the specification of combineLates discussed in the last paragraph it again publishes (-10, true) because this is just the new value which in this construction just happens to equal the old one. At that point combine publishes the valid tuple (-10, 0) and prints. In your construction, it's just the case that in the first situation the 0 gets to hasZero first but then the -10 gets to negatives first. Swift Publisher is your one-stop application for designing and printing CD labels, multipage booklets, DVD covers, jewel case inserts, spines and more.

#Swift publisher 3 for mac#
This can be seen from the docs here Apple Developer Documentation and in particular if you take a look at their example. Swift Publisher for Mac is developed by Belight. The combineLatest keeps a buffer with the latest value from each of the publishers it has combined and publishes whenever any of the two sends a new value, effectively combining it with the current or "old" value of the other one. It's not a bug, this is expected behaviour. Combine might be limited to the latest versions. Is it a bug? I think so because it's weird to have different result from the same pipeline.Įxample of valid (or what I'm considered to be valid) output: 2:: receive subscription: (PassthroughSubject)ġ:: receive subscription: (PassthroughSubject)Ĥ:: receive subscription: (CombineLatest)Įxample of invalid output: 2:: receive subscription: (PassthroughSubject) 3 - What are his strengths Swift is dynamic as they come, capable of playing on all three downs given his ability as a runner, receiver, and his improvement as a pass-blocker last season. While Combine is a complex and powerful framework with a ton of different APIs and capabilities, the Published property wrapper is one of its core aspects when it comes to UI development specifically as it lets us easily set up reactive data bindings between our models and our UI. I cannot explain it myself but most of the time negative -10 after 0 is printed twice instead of once. Let's imagine we would like to have a pipeline which will print something in case there is a negative value after previously encountered zero by using following code: let nums = PassthroughSubject()
