ios – XLForm multi-level selectors



I'm working on a very old iOS project using XLForm. I need to support a dynamic screen flow like this enclosed  image

Since XLForms is no longer on active development, I thought to ask the question here.

I have tried using XLFormOptionsObject and use a formSegueIdentifier to be customized, but have not been very useful. If anyone has experience with a similar type of implementation using XLForms, all advice is appreciated.

Page Q;
I can intercept screen C selection on screen B using formRowDescriptorValueHasChanged but how do I manually return it to screen A to update the value?


Display A
̵

1; Select Option> (press slide to screen B)

Screen B
– Option 1 (press selected option 1, the screen value for a row value is displayed)
– Option 2 (Same as option 1)
– Grouped options> (press to go to screen C)
– Option 3 (Same as Option 1)

Display C
– Option 1 from grouped options (press selects option 1, screen C&B appears to go to A and updates screen A's row value)
– Option 2 from grouped options (same as above)
