How can I convert a publisher of array a certain element, to just a publisher of said element (but with more events)?
e.g. how can I convert
AnyPublisher<[Int], Never> to AnyPublisher<Int, Never>?
I think maybe what RxSwift offers with its from operator is similar to what I want to do.
I guess I want the inverse of Combine collect?
Here is the code:
func example(publisher: AnyPublisher<[Foo], Never>) -> AnyPublisher<Foo, Never> {
return publisher
.map { $0.publisher }
.switchToLatest()
.eraseToAnyPublisher()
}
What you probably want to do is to use a FlatMap on the publisher of the Foo array, using a function which converts the Foo array to an Observable of Foo (which is where the from comes in).
.flatMap { $0.publisher }
