font size adapted to device in collection view

Hello, I have a font in a collection view that I want to scale according to device. I use the code below, that works, but when I go to another file and back to this file, the size is smaller than the original size. Anyone know to fix that?

This is my code to scale:

[login to view URL] = [login to view URL]([login to view URL] * 12 / 20)
