Show validation on each UItextfield after tapping submit button using RxSwift

Question

I am new to RxSwift and MVVM pattern, I would like to ask how do I show validation on each UItextfield after tapping submit button using RxSwift.

Your view model should have an Observable<Bool> for each text field. It if emits false then the data in the field is invalid. These Observable<Bool>s should emit values every time the button's tap Observable triggers.
