Constraints\auto layout doesnt work

hey :slight_smile:
Im using xcode 8 . The constraints doesnt work, im draggin an image view

-Lets say that the original height is 230 and width 400.

-Im choosing add new Constraints. checking the height in width and setting it to 120/170

-I also clickng resolve auto layout issued ( just updating constrants to view )

the shape stills stays the same 230/400 without changing.

is it possible for you to upgrade your xcode version? that is quite old and we wont be able to replicate it
