How to create random numbers with exceptions and that do not repeat themselves? (Swift 4) : Sorry for the English of Google Translate.
I would like to know how to make an app generate a random number with numbers determined by typing in UITextField, for example, between 25 and 35, but that do not repeat and that can not display some numbers, also determined by typing in UITextField, for example : 28, 29 and 30.
So by pressing the button he would have the numbers 25, 26, 27, 31, 32, 33, 34 and 35 to display (remembering that without repeating)

I've tried several places and courses, but I did not get a valid answer.
