UIConstraintValue
A simple Swift extension that allows different constraint values for the same traits but on different screen sizes. It has been shamelessly ripped off heavily inspired by Layout-Helper [https://github.com/tryWabbit/Layout-Helper]
Install
Add UIConstraintValue to your podspec. On the project folder, run pod install.
How to use it
Select a constraint you wish to set values for a certain device type. Add values into XCode's attribute inspector panel.
