Here's a snippet, iPad specific. If the user clicks the button while editing the TextField (cursor flashing) in dataPtView, the app crashes.

CellView:

VStack{
  Button("TagOut"){
    self.tagOut.toggle()
  }

  if self.tagOut {
    TagOutView(question: question)
  }

  if !self.tagOut{
    if question.type == "Y/N"{
      YesOrNoView(question: question)
    } else if question.type == "DataPt"{
      DataPtView(question: question)
    } else {
      RecordEntryView()
  }
  ...

DataPtView:

 ...
 TextField("Data: ", text: $collectedData)
        .onReceive(Just(collectedData)) {value in
          let filtered = value.filter {"01234567890-".contains($0)}
          if filtered != value{
            self.invalidCollectedData = true
          } else {
            self.invalidCollectedData = false
          }
  }
  ...

I'm also using an AdaptsToKeyboard ViewModifier for when CellView is covered by the keyboard.https://stackoverflow.com/questions/56491881/move-textfield-up-when-the-keyboard-has-appeared-in-swiftui

How do I prevent this from happening? If user hides the keyboard before clicking the button, everything is fine, but that isn't intuitive.
