How to create text swatch programmatically?

If, I follow method from saving controller in the product-attribute module (admin) then, I got first and the third field saved but not actual text swatch.

Try to use my code, Basically you'd need to add a select type, then convert it to Text Swatch like SwatchesSampleData module this used some functions from this module
