Question: I have this settings:

In XCode interface builder, I have added constraints. Now the red one between "S...gs" button and right "large" button is set to "greater than or equal", but it gives me error about missing constraint for position X. If I cnage this constraint to "equal" error is gone. What is wrong here? 

EDIT:
Maybe its "conflicting" with some other constrains I have. I am adding full storyboard settings for the view controller

(Plus there are also some "programatically" added constraints during execution, but those should not affect XCode storyboard)

Answer: 
As it shown up, there is no real error. Xcode reports it as an error, but at runtime on a real device it works as expected.
Try to set search button width constraint to greater or equal to 0
