How to set fixed button?

[luxystech]

Could you give any idea how to make button fixed on bottom and always over the form when scrolling?

I think you should ask this question in stackoverflow as it has little to do with XLForm.

Anyways, you should add the button you want to the form's parent view(probably your viewcontroller's view) and setup the appropriate constraints to have the button below the form and at the bottom of the view.
I think it's pretty straightforward but you can search stackoverflow and you'll find lot's of threads, like this one.
