title: iOS autolayout - size with less then or equal Inequality constraint ambiguity
body: <p>I can not understand why following setup gives me the Inequality constraint ambiguity error. The general idea (although simplified in this question) is to pin the View to the top and left, give it fixed height and variable width. Thus, 4 constraints have been added: 3 with equal values (for top, left and height) and 1 with less than or equal. And it gives me that error. Finally, what I am trying to achieve, is to put other new to the right of this View, and specify the spacing between them. So, whenever Left view changes the width, the right View will change the X.</p>
