title: Stack button fail
body: <p>Swift 2.2 Xcode 7.3.1. iOS 9. Storyboard. I have 7 rows of four labels across. I was intending to select each row to place it in a stack. Saw this technique in Hagerty's iTunes U (Stanford). Each time I select a row and press the button to add the four across to a stack, it makes these huge rectangles... They have a width of 127,000,000. I keep trying different things, adding all suggested constraints, getting rid of all contstraints, etc.</p>
  
  <p>Any idea what I am doing wrong? TIA</p>
  
  <p>Sorry, I'm apparently not allowed to add images as yet here... The rectangles on the View Controller are all UILabels. When I select a row of them and press the Stack button, next to pin, etc., it appears to make one wide rectangle, all 4 on top of each other, this last time is was 27,216,026 pixels across. I think the comment about not using "suggested" constraints is probably a clue... there certainly seem to be more than necessary. There are also some where I tried to delete a constraint where the constraint item appears to be dimmed. There are one or two where the dimmed one, and an exact copy of the dimmed are both there...</p>
  
  <p>There are no images on the view... the only button is up top, a "Back" button.</p>
