UITextField EditingDidBegin triggered twice on IOS 14.4

Question

I have two textfields. I want to open a bottomsheet when the first textfield is tapped. And the other textfield is accepting user input regularly.

This is my trigger when the produklistrikDropdown text field with edittingDidBegin.

produkListrikDropDown.rx.controlEvent(.editingDidBegin)
            .subscribe(onNext:{
                self.dismissKeyboard()
                print("produk Listrik Field did begin")
                self.viewModel.showProdukListrik()
            })
            .disposed(by: disposeBag)

And after I choose a product from the bottom sheet it just change the text of the field to the one i choose.

viewModel.currentProdukListBehaviorSubject
            .map{$0?.rawValue}
            .subscribe(onNext: { [unowned self] in
                if produkListrikDropDown.text != $0 {
                    produkListrikDropDown.text = $0
                }
            })
            .disposed(by: disposeBag)

This is my second textfield configuration. Just a regular textfield receiving input from the user.

idPelangganField.rx.text
            .bind(to: viewModel.currentIdPelangganBehaviorSubject)
            .disposed(by: disposeBag)

What Happen

When I tapped the first textfield and choose a product, its acting okay. But when I tapped the second textfield and tapped back to the first textfield, the edittingDidBegin on the first textfield triggered twice. This doesn't happen on IOS 12.4.

Answer 1

I've found a better way without sacrificing the use of textfield. Like @Daniel T. said, that we can use a tap gesture recognizer on it. I put a Tag Gesture Recognizer for the UITextField and set it to receive touch down events. It eliminates any side effects of the textFieldShouldBeginEditting(_:) and also not use any RxSwift to make the call.
