You cannot use auto layout and change the center / frame of things; those are opposites. Do one or the other - not both.

So, you don't have to turn off auto layout, but if you don't, then you must use auto layout, and auto layout only, to position things.

When you move the label, do not change its center - change its constraints. Or at least, having changed its center, change its constraints to match.

Otherwise, when layout occurs, the constraints will put it back where you have told them to put it. And layout does occur when you change the text, and at many other times.
