title: How to set a negative Align Center X or Y value in Interface Builder in Xcode 6.4?
body: <p>I'm trying to set a negative value in Xcode 6.4 in an Interface Builder auto layout constraint as follows:</p>
  
  <p><a href="https://i.stack.imgur.com/olG00m.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/olG00m.png" alt="enter image description here"></a></p>
  
  <p>If I type "-50.0", Xcode registers the negative value (changes it to "-50"), but defaults to 0 when I close the pop up window. If I type "-50" directly, it instantly changes to 0.</p>
  
  <p>How can I enter negative values? I'm using Xcode Version 6.4 (6E35b), but I'm also experiencing this in Version 7.0 beta 6 (7A192o). I have English as preferred language, region as <code>Finland - Finnish</code> and using a Finnish keyboard.</p>
