How to Disable the button tap in 5 seconds by using rxSwift? - rx-swift

Question

rxSwift version:
pod 'RxSwift', '6.2.0'
pod 'RxCocoa', '6.2.0'
TrueBtn.rx.tap.throttle(.seconds(5), scheduler: MainScheduler.instance)
.subscribe(onNext: { [weak self] in
print("TrueBtn-true")
}).disposed(by: bag)
How to Disable the button tap in 5 seconds by using rxSwift?
There is a false button in the same view.
FalseBtn.rx.tap.throttle(.seconds(5), scheduler: MainScheduler.instance)
.subscribe(onNext: { [weak self] in
print("FalseBtn-false")
}).disposed(by: bag)
I click the true button and after 1 second click the true button again. Then I click the false button.
Now the result is :
TrueBtn-true
wait for 1 second
FalseBtn-false
wait 4 seconds
TrueBtn-true
I want this:
TrueBtn-true
wait for 1 second
FalseBtn-false
wait more than 5 seconds
print nothing
parameter latest: Should latest element received in a due time wide time window since last element emission is emitted.
Can I write some code to set the latest
value to false without changing the rx-swift api?

The use case is a bit confusing to me. I'm going to assume it's something like.
When the user taps either the true or false button, they have 5 seconds to change their mind and tap the other button. Once the grace period is up, the app will print their choice and disable further taps.
Some marble diagrams to demonstrate:
User makes a selection and doesn't change their mind.
true: --T-----
false: --------
result: -------T|
User makes a selection and changes their mind before the 5 seconds are up.
true: --T---------
false: ------F-----
result: -----------F|
User makes a selection and tries to change their mind after 5 seconds.
true: --T-----------
false: --------F-----
result: -------T|
Here is the code that will do the above:
func useCase(trueButton: Observable<Void>, falseButton: Observable<Void>, scheduler: SchedulerType) -> Observable<Bool> {
Observable.merge(
trueButton.map { true },
falseButton.map { false }
)
.debounce(.seconds(5), scheduler: scheduler)
.take(1)
}
