ios - Check if 3D touch is supported and enabled on the iOS9 device

I tried to access the trait collection and check "forceTouchCapability", but "forceTouchCapability" simply checks to see if the device is iOS 9.0 or greater.

So, this means that on any device with iOS 9, force touch is 'available'. I need to a way to check if 3D touch is actually supported on the users device (iPhone 6s) and I need to make sure that the 3D Touch option is actually enabled in the accessibility settings.

I was accidentally casting forceTouchCapability to a BOOL (using it as a return value to my method that was set to return a boolean). I needed to check if forceTouchCapability was equal to UIForceTouchCapabilityAvailable.

Instead of:

return [[MyView traitCollection] forceTouchCapability];

I need:

return [[MyView traitCollection] forceTouchCapability] == UIForceTouchCapabilityAvailable;
