I have such code as below. How can I achieve it in one chain, without using subscribe on timer? I would like to attach 'timerInterval' to 'timer' and then call subscribe.
var timerInterval: BehaviorRelay<String> = BehaviorRelay(value: "")
...
func doLogic() {
let timer = Observable<Int>.interval(0.05, scheduler: MainScheduler.instance)
timer.subscribe({ [weak self] value in
let doubleValue = Double(value.element ?? 0)
let dividedValue = doubleValue / 20.0
let text = String(format: "%.2f", dividedValue)
self?.timerInterval.accept(text)
}).disposed(by: disposeBag)
}
You'd go for map operator. I'm not sure why you need BehaviourRelay
but I'd do something even more simpler:
let timer = Observable<Int>.interval(0.05, scheduler: MainScheduler.instance)
var timerInterval: Observable<String> {
return timer.map { value -> String in
let doubleValue = Double(value.element ?? 0)
let dividedValue = doubleValue / 20.0
let text = String(format: "%.2f", dividedValue)
return text
}
}
