Question

Someone knows where to set adjustsFontSizeToFitWidth in the utilities (right) pane when editing the storyboard?

Answer 1

Select your label in the storyboard, and set the drop down to Minimum Font Size. Then in the text field, enter the lowest size your label should drop to to try to fit the contents onscreen:

Answer 2

Go to attributes inspector on your TextField and under minimum font size drop down menu there is a checkbox Adjust to Fit.
