Ruby problems with formotion module - iphone

Question

There is an app written in ruby that I need to get running. It worked before IOS11 but is now throwing errors. I have formotion installed and all the appropriate gems and the SDK. I am having trouble getting the compiler to recognize that there is a formotion gem with things inside it.
I am getting an uncaught exception "Name Error" and it says that the variable im trying to instantiate within the formotion class is an uninitialized constant.
Any help with this error would be appreciated.
Here are some bit of the code, the error points to row.text_field.resignFirstResponder
module RowType
class PickerWithDoneRow < PickerRow
include RowType::ItemsMapper
def after_build(cell)
super
keyboardDoneButtonView = UIToolbar.new
keyboardDoneButtonView.barStyle = UIBarStyleBlack
keyboardDoneButtonView.tintColor = "#000".uicolor
keyboardDoneButtonView.translucent = false
keyboardDoneButtonView.sizeToFit
# keyboardDoneButtonView.barTintColor = "#BFC3C8".uicolor
keyboardDoneButtonView.barTintColor = "#EFEFF4".uicolor
doneButton = UIBarButtonItem.alloc.initWithTitle("Done", style:UIBarButtonItemStylePlain, target:self, action: 'picker_done_clicked')
spacer1 = UIBarButtonItem.alloc.initWithBarButtonSystemItem(UIBarButtonSystemItemFlexibleSpace, target:self, action: nil)
spacer = UIBarButtonItem.alloc.initWithBarButtonSystemItem(UIBarButtonSystemItemFlexibleSpace, target:self, action: nil)
keyboardDoneButtonView.setItems([spacer, spacer1, doneButton])
row.text_field.inputAccessoryView = keyboardDoneButtonView
end
def picker_done_clicked
row.text_field.resignFirstResponder
end
end
end
