How do I use new Touch.pressure?

Touch.pressure was introduced in patch version 5.2.2p1. I am trying to use it experimentally, just to see what is being returned. The Unity editor throws no errors, but when I try to build using Cloud Build (set to Use Latest for Xcode and Unity version) I get the following:

error CS1061: Type UnityEngine.Touch' does not contain a definition for pressure’ and no extension method pressure' of type UnityEngine.Touch’ could be found (are you missing a using directive or an assembly reference?)

The project is set up to require iOS 9.0 minumum.

Here’s my code - very basic, just updating a UI Text element with the touch pressure every frame.

        float touchPressure;

        void Update()
            if (Input.touchCount > 0)
                touchPressure = Input.GetTouch(0).pressure;
                pressureText.text = touchPressure + "";

There isn’t any documentation about this yet, so any help would be greatly appreciated!

It seems that it’s a cloud build issue. I had assumed that setting it to “Latest” would use the latest available Unity engine, but it seems that it uses the latest f build - to use a patch build you have to select it manually.
