Search a value in Array of Observable

Question

I'm having array of Bool Observables in Rxswift.

let rxBoolObservableArray: [Observable<Bool>] = [Observable<Bool>]()

Now, How to get If any of the element is false?

Answer 1

Here is allSatisfy extension based on @DanielT answer. It might be suitable for your problem:

extension Array where Iterator.Element: ObservableType {

    func allSatisfy(_ predicate: @escaping (Iterator.Element.E) throws -> Bool) -> Observable<Bool> {
        return Observable.combineLatest(self) { try $0.allSatisfy(predicate) }
    }
}

example usage:

rxBoolObservableArray
    .allSatisfy { $0 } // { $0 == true }
    .subscribe(onNext: { areTestsPassing in
        print(areTestsPassing)
    })
    .disposed(by: disposeBag)
